The maximum aggregate nominal amount of all Notes from time to time outstanding under the Programme will not exceed €9,000,000,000 (or its equivalent in other currencies calculated as described in the Programme Agreement described herein), subject to increase as described herein.

References in this Base Prospectus to the relevant Dealer shall, in the case of an issue of Notes being (or intended to be) subscribed by more than one Dealer, be to all Dealers agreeing to subscribe such Notes. An investment in Notes issued under the Programme involves certain risks. For a discussion of these risks see “Risk Factors”.

The CSSF only approves this Base Prospectus as meeting the standards of completeness, comprehensibility and consistency imposed by the Prospectus Regulation. Approval by the CSSF should not be considered as an endorsement of the Issuer or of the quality of the Notes. Investors should make their own assessment as to the suitability of investing in the Notes.

By approving this Base Prospectus, the CSSF assumes no responsibility and gives no undertaking for the economic and financial soundness of the transactions contemplated by this Base Prospectus or the quality or solvency of the Issuer in line with the provisions of Article 6 (4) of the Luxembourg Law on Prospectuses for securities. Application has been made to the Luxembourg Stock Exchange for Notes issued under the Programme to be admitted to trading on the Luxembourg Stock Exchange’s regulated market and to be listed on the Official List of the Luxembourg Stock Exchange. References in this Base Prospectus to Notes being listed (and all related references) shall mean that such Notes have been admitted to trading on the Luxembourg Stock Exchange’s regulated market and have been admitted to the Official List of the Luxembourg Stock Exchange. The Luxembourg Stock Exchange’s regulated market is a regulated market for the purposes of the Markets in Financial Instruments Directive (Directive 2014/65/EU).

The obligation to supplement this Base Prospectus in the event of a significant new factor, material mistake or material inaccuracy does not apply when this Base Prospectus is no longer valid. The requirement to publish a prospectus under the Prospectus Regulation (as defined under “Important Information” below) only applies to Notes which are to be admitted to trading on a regulated market in the European Economic Area (the EEA) and/or offered to the public in the EEA other than in circumstances where an exemption is available under Article 1(4) and/or 3(2) of the Prospectus Regulation. References in this Base Prospectus to Exempt Notes are to Notes for which no prospectus is required to be published under the Prospectus Regulation.

Notes issued under the Programme may be rated or unrated by any one or more of the rating agencies referred to above. Where a Tranche of Notes is rated, such rating will be disclosed in the Final Terms (or Pricing Supplement, in the case of Exempt Notes) and will not necessarily be the same as the rating assigned to the Programme by the relevant rating agency. A security rating is not a recommendation to buy, sell or hold securities and may be subject to revision, suspension or withdrawal at any time by the assigning rating agency. Please also refer to “Risks related to the Market Generally – Credit ratings assigned to the Issuer or any Notes may not reflect all the risks associated with an investment in those Notes” in the “Risk Factors” section of this Base Prospectus.

When used in this Base Prospectus, Prospectus Regulation means Regulation (EU) 2017/1129, and UK Prospectus Regulation means Regulation (EU) 2017/1129 as it forms part of domestic law by virtue of the the European Union (Withdrawal) Act 2018 (EUWA).

The Issuer (the Responsible Person) accepts responsibility for the information contained in this Base Prospectus and the Final Terms for each Tranche of Notes issued under the Programme. To the best of the knowledge of the Issuer (having taken all reasonable care to ensure that such is the case) the information contained in this Base Prospectus is in accordance with the facts and does not omit anything likely to affect the import of such information.

This Base Prospectus is to be read in conjunction with all documents which are deemed to be incorporated by reference in it (see “Documents Incorporated by Reference”). This Base Prospectus shall be read and construed on the basis that those documents are incorporated and form part of this Base Prospectus.

Other than in relation to the documents which are deemed to be incorporated by reference (see “Documents Incorporated by Reference”), the information on the websites to which this Base Prospectus refers does not form part of this Base Prospectus and has not been scrutinised or approved by the CSSF.

No representation, warranty or undertaking, express or implied, is made by any of the Dealers or by any of their respective affiliates (including parent companies) or the Trustee and no responsibility or liability is accepted by any of the Dealers or by any of their respective affiliates (including parent companies) or the Trustee as to the accuracy or completeness of the information contained or incorporated by reference in this Base Prospectus or of any other information provided by the Issuer in connection with the Programme. None of the Dealers or any of their respective affiliates (including parent companies) or the Trustee accepts any liability in relation to the information contained or incorporated by reference in this Base Prospectus or any other information provided by the Issuer in connection with the Programme.

This Base Prospectus contains industry and customer-related data as well as calculations taken from industry reports, market research reports, publicly available information and commercial publications. It is hereby confirmed that (a) to the extent that information reproduced herein derives from a third party, such information has been accurately reproduced and (b) insofar as the Issuer is aware and is able to ascertain from information derived from a third party, no facts have been omitted which would render the information reproduced inaccurate or misleading.

No person is or has been authorised by the Issuer, any Dealer or the Trustee to give any information or to make any representation not contained in or not consistent with this Base Prospectus or any other information supplied in connection with the Programme or the Notes and, if given or made, such information or representation must not be relied upon as having been authorised by the Issuer, any of the Dealers or the Trustee.

Neither this Base Prospectus nor any other information supplied in connection with the Programme or any Notes (a) is intended to provide the basis of any credit or other evaluation or (b) should be considered as a recommendation by the Issuer, any of the Dealers or the Trustee that any recipient of this Base Prospectus or any other information supplied in connection with the Programme or any Notes should purchase any Notes. Each investor contemplating purchasing

any Notes should make its own independent investigation of the financial condition and affairs, and its own appraisal of the creditworthiness, of the Issuer. Neither this Base Prospectus nor any other information supplied in connection with the Programme or the issue of any Notes constitutes an offer or invitation by or on behalf of the Issuer, any of the Dealers or the Trustee to any person to subscribe for or to purchase any Notes.

Neither the delivery of this Base Prospectus nor the offering, sale or delivery of any Notes shall in any circumstances imply that the information contained in it concerning the Issuer is correct at any time subsequent to its date or that any other information supplied in connection with the Programme is correct as of any time subsequent to the date indicated in the document containing the same. The Dealers and the Trustee expressly do not undertake to review the financial condition or affairs of the Issuer during the life of the Programme or to advise any investor in Notes issued under the Programme of any information coming to their attention. Investors should review, inter alia, the most recently published documents incorporated by reference into this Base Prospectus when deciding whether or not to purchase any Notes.

IMPORTANT – EEA RETAIL INVESTORS – If the applicable Final Terms in respect of any Notes (or the applicable Pricing Supplement, in the case of Exempt Notes) specify that "Prohibition of Sales to EEA Retail Investors" is applicable, the Notes are not intended to be offered, sold or otherwise made available to and should not be offered, sold or otherwise made available to any retail investor in the European Economic Area (EEA). For these purposes, a retail investor means a person who is one (or more) of: (i) a retail client as defined in Article 4(1) of Directive 2014/65/EU (as amended, MiFID II); or (ii) a customer within the meaning of Directive (EU) 2016/97 (the Insurance Distribution Directive), where that customer would not qualify as a professional client as defined in Article 4(1) of MiFID II; or (iii) not a qualified investor as defined in the Prospectus Regulation. Consequently no key information document required by Regulation (EU) No 1286/2014 (as amended, the PRIIPs Regulation) for offering or selling the Notes or otherwise making them available to retail investors in the EEA has been prepared and therefore offering or selling the Notes or otherwise making them available to any retail investor in the EEA may be unlawful under the PRIIPs Regulation.

IMPORTANT – UK RETAIL INVESTORS – If the applicable Final Terms in respect of any Notes (or the applicable Pricing Supplement, in the case of Exempt Notes) specify that "Prohibition of Sales to UK Retail Investors" is applicable, the Notes are not intended to be offered, sold or otherwise made available to and should not be offered, sold or otherwise made available to any retail investor in the United Kingdom (UK). For these purposes, a retail investor means a person who is one (or more) of: (i) a retail client, as defined in point (8) of Article 2 of Regulation (EU) No 2017/565 as it forms part of domestic law by virtue of the EUWA; or (ii) a customer within the meaning of the provisions of the FSMA and any rules or regulations made under the FSMA to implement the Insurance Distribution Directive, where that customer would not qualify as a professional client, as defined in point (8) of Article 2(1) of Regulation (EU) No. 600/2014 as it forms part of domestic law by virtue of the EUWA; or (iii) not a qualified investor as defined in Article 2 of Regulation (EU) 2017/1129 as it forms part of domestic law by virtue of the EUWA. Consequently no key information document required by Regulation (EU) No 1286/2014 as it forms part of domestic law by virtue of the EUWA (the UK PRIIPs Regulation) for offering or selling the Notes or otherwise making them available to retail investors in the UK has been prepared and therefore offering or selling the Notes or otherwise making them available to any retail investor in the UK may be unlawful under the UK PRIIPs Regulation.

MiFID II product governance / target market – The Final Terms in respect of any Notes may include a legend entitled “MiFID II Product Governance” which will outline the target market assessment in respect of the Notes and which channels for distribution of the Notes are appropriate. Any person subsequently offering, selling or recommending the Notes (a distributor) should take into consideration the target market assessment; however, a distributor subject to MiFID II is responsible

for undertaking its own target market assessment in respect of the Notes (by either adopting or refining the target market assessment) and determining appropriate distribution channels.

A determination will be made in relation to each issue about whether, for the purpose of the MiFID I I Product Governance rules under EU Delegated Directive No. 2017/593 (the MiFID II Product Governance Rules), any Dealer subscribing for any Notes is a manufacturer in respect of such Notes, but otherwise neither the Joint Arrangers nor the Dealers nor any of their respective affiliates will be a manufacturer for the purpose of the MiFID II Product Governance Rules.

UK MiFIR product governance / target market – The Final Terms in respect of any Notes (or Pricing Supplement, in the case of Exempt Notes) may include a legend entitled “UK MiFIR Product Governance” which will outline the target market assessment in respect of the Notes and which channels for distribution of the Notes are appropriate. Any person subsequently offering, selling or recommending the Notes (a distributor) should take into consideration the target market assessment; however, a distributor subject to the FCA Handbook Product Intervention and Product Governance Sourcebook (the UK MiFIR Product Governance Rules) is responsible for undertaking its own target market assessment in respect of the Notes (by either adopting or refining the target market assessment) and determining appropriate distribution channels.

A determination will be made in relation to each issue about whether, for the purpose of the UK MiFIR Product Governance Rules, any Dealer subscribing for any Notes is a manufacturer in respect of such Notes, but otherwise neither the Joint Arrangers nor the Dealers nor any of their respective affiliates will be a manufacturer for the purpose of the UK MIFIR Product Governance Rules.

Selling Restrictions: There are restrictions on the offer, sale and transfer of the Notes in the United States, the United Kingdom, the EEA (including, for these purposes, France and Italy) and Japan, and such other restrictions as may be required in connection with the offering and sale of a particular Tranche of Notes (see “Subscription and Sale”).

United States Selling Restrictions: Regulation S, Category 2. TEFRA C or D or TEFRA not applicable, as specified in the applicable Final Terms (or applicable Pricing Supplement, in the case of Exempt Notes).

RISK FACTORS

In purchasing Notes, investors assume the risk that the Issuer may become insolvent or otherwise be unable to make all payments due in respect of the Notes. There is a wide range of factors which, either individually or together could result in the Issuer becoming unable to make all payments due. It is not possible to identify all such factors or to determine which factors are most likely to occur, as the Issuer may not be aware of all relevant factors and certain factors which it currently deem not to be material may become material as a result of the occurrence of events outside the Issuer’s control. The Issuer has identified in this Base Prospectus a list of the factors which could materially adversely affect its business and ability to make payments due.

In addition, factors which are material for the purpose of assessing the market risks associated with Notes issued under the Programme are also described below.

Prospective investors should also read the detailed information set out elsewhere in this Base Prospectus and reach their own views prior to making any investment decision.

FACTORS THAT MAY AFFECT THE ISSUER’S ABILITY TO FULFIL ITS OBLIGATIONS UNDER NOTES ISSUED UNDER THE PROGRAMME

The risks below have been classified into the following categories:

– Risks relating to the Issuer’s financial position;

– Risks relating to the Issuer’s business activity and industry;

– Risks related to the internal control of the Issuer; and

– Risks related to the political, environmental, social and governance environment of the issuer.

Risks relating to the Issuer’s financial position

The Issuer may be exposed to financial risks.

The Terna Group is exposed to financial risks: market risk (interest rate risk, exchange rate risk and inflation risk), liquidity risk and credit risk. If such risks materialise, the Issuer’s cash flows may be affected. In accordance with the policies approved by its Board of Directors, the Issuer has established responsibilities and operational procedures in order to manage such financial risks and agree the measures to be adopted. Terna’s risk management policies aim to identify and analyse the risks to which the Terna Group is exposed, setting appropriate limits and controls and monitoring risks and compliance with such limits. These policies and their relevant systems are reviewed on a regular basis in order to reflect any changes in market conditions and in the activities of the Terna Group.

Liquidity risk

Liquidity risk is the risk that the Terna Group might encounter difficulty in discharging its obligations in respect of its financial liabilities and operating cycle. Liquidity risk management seeks to ensure adequate coverage of borrowing requirements by obtaining adequate credit lines and appropriate management of any surplus liquidity.

Ratings associated risk

Terna is currently rated by S&P, Moody’s and Scope. Generally, a credit rating assesses the creditworthiness of an entity and informs investors about the probability of the entity being able to redeem invested capital. It is not a recommendation to buy, sell or hold securities, it may be revised or withdrawn by the rating agency at any time and does not comment on the market price, marketability, investor preference or suitability of any security.

Credit ratings play a critical role in determining the costs for entities accessing the capital markets in order to borrow funds and the rate of interest they can achieve. A decrease in credit ratings by S&P, Moody’s or Scope may increase borrowing costs or even jeopardise further issuance.

The price of the existing bonds may deteriorate following a downgrade of the Issuer’s credit ratings. In addition, the Issuer's credit ratings are potentially exposed to risk in reductions of the sovereign credit rating of the Republic of Italy. On the basis of the methodologies used by S&P, Moody’s and Scope, a potential downgrade of Italy's credit rating may have a potential knock-on effect on the credit rating of Italian issuers such as the Issuer and increase the likelihood that the credit rating of Notes issued under the Programme could be downgraded, with a consequent adverse effect on their market value.

Interest Rate Risk

Interest rate risk is represented by the uncertainty associated with interest rate fluctuations. This is the risk that a change in market interest rates may produce effects on the fair value or on the future cash flows of financial instruments. Terna’s main source of interest rate risk is associated with its borrowings and related hedges in the form of derivative instruments that generate financial expenses.

Terna’s borrowing strategy focuses on long-term loans whose maturities reflect the useful life of company assets. The Issuer pursues an interest rate risk hedging policy that aims at guaranteeing that the percentage of debt represented by fixed rate liabilities is at least 40 per cent., as provided for in the relevant policies.

Interest rate risk is mitigated through derivatives, which hedge the risk connected with movements in interest rates relating to long-term borrowing.

Credit Risk

Credit risk is the risk that one of the counterparties of a financial or commercial transaction could cause a financial loss by failing to discharge an obligation. It is mainly generated by trade receivables and by the financial investments of the Issuer.

The credit risk originated by open positions on transactions in derivatives is considered to be marginal since the counterparties, in compliance with the financial risk management policies adopted, are leading international banks with high ratings.

Terna provides its services essentially to counterparties considered solvent by the market, and therefore with a high credit standing, and does not have high concentrations of credit risk.

With specific reference to credit risk associated to trade receivables, the management of such risk is driven by the applicable regulations, including provisions of the Regulatory Authority for Energy, Networks and the Environment (Autorità di Regolazione per Energia Reti e Ambiente, hereinafter referred to as the ARERA) Resolution 111/06.

Exchange risk

Although the focus of the Terna Group is investing in the domestic grid, Terna aims to take advantage of opportunities for international expansion by leveraging its core competencies developed in Italy as a TSO, where such competencies are of significant importance in its home country. Due to these activities, Terna has a marginal exposure to the exchange rate risks in relation to cash flows related to investments, revenues, costs, financial income or expenses denominated in foreign currencies, such as cash flows related to the purchase or sale of equity participations. Such exposure is mitigated through highly liquid and easy-to-price derivatives, such as forwards and options.

Inflation risk

As regards inflation risk, the rates established by the regulator to provide a return on Terna’s activities are determined to cover the allowed costs. Such cost components are updated on an annual basis to take into account the impact of inflation.

Risks relating to the Issuer’s business activity and industry

The Issuer’s revenues and the conduct of Regulated Activities substantially depend on the actions and decisions of the regulatory authorities in Europe and Italy.

Remuneration criteria for the electricity transmission, distribution, metering and dispatching services, as well as the regulation related to the quality of the transmission service, are set by ARERA. Within the scope of these regulations there are a number of variables that could impact on the Terna Group's performance (for further details please see section “Description of the Issuer – Tariff System”).

In addition, with respect to the electricity transmission, the payments due to the Terna Group are collected directly by the Terna Group invoicing the Italian electricity distributors. Accordingly, any failure or delay in collecting tariffs from the Italian electricity distributors may have an adverse effect on the Terna Group’s financial condition and results of operations. Also, distributors or other participants in the electricity sector may request the recalculation of tariffs invoiced to them. If any such recalculation is required, it is possible that the annual fees related to the recalculation period may be reduced as a result and/or such recalculation may have an adverse effect on the Terna Group’s revenues, financial position or results of operations.

The Terna Group is also required to comply with the guidelines and directives of the Ministry of Economic Development (now the Ministry of Ecological Transition) relating to the operation, maintenance and development of the Terna Group’s Grid, including the level of capital expenditure required for such activities. Future guidelines or directives by the Ministry of Economic Development (now the Ministry of Ecological Transition) over which the Issuer has no control, including those requiring investments or the incurrence of capital expenditures, may increase the Terna Group’s costs or, otherwise, adversely affect its financial condition and results of operations.

The Issuer may be affected by appeals against provisions adopted by it following Resolutions by the ARERA. The Issuer, as concessionaire of transmission and dispatching services, may adopt measures or undertake actions in order to comply with Resolutions of the ARERA. Third parties affected by such measures and actions may seek to appeal against such measures and actions in administrative proceedings. In the event that such proceedings lead to the annulment of measures and actions taken by the Issuer, the Issuer is unable to predict the impact of such judgments on its business, financial situation or performance, even if the relevant economic costs may be recognised, under certain conditions, by the ARERA.

The failure of the Terna Group’s Grid or any impairment in the quality of the Issuer’s services may adversely affect the Issuer’s revenues and expose the Issuer to uncapped liabilities. The Terna Group's

operations are exposed to the risk of unexpected service interruptions caused by external events that are beyond Terna’s control, such as accidents, defects or breakdowns involving control systems or other equipment, deteriorating plant performance, natural disasters, terrorist attacks and other extraordinary events of such kind. Repairs to the sections of the National Transmission Grid owned by the Terna Group and any claims for compensation by third parties as a result of such events could give rise to expenses if the Terna Group is found to be responsible.

Moreover, the Terna Group may incur penalties and damage requests with reference to the quality of the transmission services (see also section “Description of the Issuer – Tariff System”).

The Issuer’s results may be adversely affected by the dynamics of the volume of electricity transmitted and/or dispatched by the National Transmission Grid.

Risks related to the concession governing the transmission and dispatching activities conducted by the Issuer

The Issuer conducts the transmission and dispatching activities, including the management of the National Transmission Grid pursuant to a concession (see also sections “Description of the Issuer – History and development” and “Description of the Issuer – Legislative and Regulatory Framework”).

The concession will expire in 2030 and may be renewed for the same duration (i.e. 25 years). The Ministry of Economic Development can impose suspension or revocation of such concession in the case of an event of default or a breach by the Issuer that can seriously affect the performance of the electrical service. It can also order the revocation of the concession if it is no longer appropriate for the pursuit of the public interest (see also section “Description of the Issuer – Legislative and Regulatory Framework”).

The Issuer’s inability to retain ownership of the concession or a renewal thereof at less favourable terms could materially and adversely affect its future results of operations and cash flows, as well as its financial conditions.

The Issuer may be exposed to risks deriving from Non-Regulated and International Activities

Through Non-Regulated domestic activities, Terna Group is oriented to support energy transition, leveraging on its competences so as to offer a portfolio of products/services in line with the market opportunities in turn available. Furthermore, the small average size of the deals (or the selection of strategic counterparties for the big ones) limits the impact on the results of Non-Regulated Activities.

In relation to International Activities the Terna Group/Issuer has acquired, and will acquire, the necessary financial resources executing the relevant project finance documentation. In this respect, it is worth noting that the Issuer may be required to compensate, indemnify and hold harmless the counterparties involved in the international projects, from damages suffered by them, as result of any inaccuracy or breach of any representation or warranty given by the Issuer and/or of any breach of any covenant or agreement or in relation to any claim, contingency or liability of the Terna Group/Issuer. Such claims could materially and adversely affect the Issuer’s business, results of operations and financial condition and reputation.

In addition, possible changes to the relevant legislative or regulatory framework (in Italy or abroad) may, however, make investments in this sector less attractive and, consequently, lead to a decrease in market opportunities for the Terna Group's Non-Regulated Activities, affecting its revenues and results of Non-Regulated Activities.

At least, referring to Tamini and Brugg Kabel business (both as defined in section “Description of the Issuer – Organisational Structure”, although this is relatively small size within the Terna Group, any

changes on the market conditions and any possible claims related to the production and/or the supply of industrial and power transformers and cables could have a material adverse effect on the revenues and results of these specific businesses. For further details on such Non-Regulated and International businesses please see section “Description of the Issuer – Issuer’s Business”.

Risks connected with failing to meet infrastructure development objectives

The Issuer’s ability to develop its infrastructure and to implement its projects is subject to many unforeseeable events linked to operational, economic, and regulatory factors which are outside its control. In addition, the Issuer is unable to guarantee that all the relevant authorisations and permits will be granted or issued within the expected timeframe and that, once granted or issued, these will not be revoked.

Moreover, the Issuer cannot guarantee that any planned projects will be started, completed or lead to the expected benefits in terms of tariffs. Furthermore, any such development projects may require greater investments or longer timeframes than those originally planned, affecting the Issuer’s financial position and results.

Public authorities, residents and local communities may oppose new developments or projects to be executed by the Issuer, on the grounds that new infrastructures may impact the land that will host them. Such opposition may take the form of legal proceedings or protests and/or public opposition. The occurrence of any such challenges or protests during the approval process or the execution of new projects could lead to significant delays, increases in investment costs, and, potentially, legal proceedings.

Risks associated with Terna Group’s transactions involving Countries and Activities targeted by Sanctions

Following the Terna Group’s acquisition of Tamini Group (as defined in section “Description of the Issuer – Organisational Structure”) on 20 May 2014, the Terna Group became aware that the Tamini Group has entered into certain transactions and conducts (Original Sanctionable Transactions) involving, inter alia, third parties (I) located in countries that are or were targeted by sanctions (Sanctioned Countries) or (II) that are or were targeted by any applicable laws, regulations or orders concerning any trade, economic or financial sanctions, embargoes or restrictions adopted, enacted or enforced by or in the (a) Security Council of the United Nations, (b)the United States of America, (c) the European Union, (d) any Member State of the European Union, (e) Her Majesty's Treasury of the United Kingdom or (f) any body, agency or authority from or acting on behalf of any of letters (a) to (e) above (Sanctions).

After the acquisition, the Tamini Group, with a view of preserving its market shares and commercial reputation, continued and is continuing its commercial activities connected, inter alia, to some international counterparties and/or Sanctioned Countries acquiring new contracts potentially subject to Sanctions (jointly, together with the Original Sanctionable Transactions, the Sanctionable Transactions).

In this regard, for the first quarter of 2021, the amount of revenues generated by the Tamini Group and derived from Sanctionable Transactions was less than 0.5 per cent. of the consolidated revenues of the Terna Group.

In addition, in light of the continuous evolution of any legislation applicable to Terna Group in any area of interest of Terna Group and with reference to any related transaction and activity of Terna Group - including any transaction involving Brugg Kabel AG, following its acquisition by the Issuer through its subsidiary Terna Energy Solutions S.r.l. on 29 February 2020 - (the Activities), and considering that the complex legislation is not always consistent across jurisdictions (such as (i) Council Regulation

(CE) 2271/1996 and/or any associated and applicable national law, instrument and/or regulation related thereto as amended from time to time (the EU Blocking Regulation); (ii) any law or regulation implementing the EU Blocking Regulation in any member state of the European Union; or (iii) any similar blocking or anti-boycott law or regulation in the United Kingdom), the Issuer, directly or indirectly through its subsidiaries, including Tamini Group, cannot exclude that the Activities, including Sanctionable Transactions, will be determined to be prohibited by Sanctions.

If any of the Sanctionable Transactions or the Activities – or any future transactions in which Tamini or any other member of the Terna Group engages – are determined to be prohibited by applicable laws or regulations, the Tamini Group or the Terna Group could itself be subject to penalties, in which case the Terna Group’s reputation, financial condition and future business prospects could be adversely affected.

The Terna Group is also aware of initiatives by certain U.S. states and U.S. institutional investors, such as pension funds, to adopt laws, regulations or policies requiring divestment from, or reporting of interests in, companies that do business with countries designated as states sponsoring terrorism. If any of the Sanctionable Transactions or the Activities are determined to fall within the scope of these laws, regulations or policies, resulting sales of the Terna Group’s securities could have an adverse effect on the price of the Terna Group’s securities. Furthermore, investors in the Terna Group’s securities could incur reputational risk or other risks as the result of the Terna Group’s dealings in or with countries, including the Sanctioned Countries, or persons that are the subject of Sanctions.

Changes in the above-mentioned regulatory environment or in the implementation thereof are unpredictable and consequently the potential effects of these events on the Issuer’s business, financial condition, results of operations or cash flows cannot be foreseen.

For further details please see “Description of the Issuer” – “Business Reputation Intelligence”.

Risks associated with pending legal proceedings

The Terna Group is involved, both as plaintiff and defendant, in civil and administrative proceedings, including contractual, human resources, environmental, regulatory and health matters that arise in the ordinary course of the Terna Group’s business, as well as in criminal proceedings.

Due to their nature, the Issuer is not able to predict the ultimate outcomes of the proceedings currently pending against members of the Terna Group, some of which may be unfavourable and may require the Terna Group to pay damages to the plaintiff, incur costs for the modification of parts of the Terna Group’s Grid or temporarily remove parts of the Terna Group’s Grid from service (see also section “Description of the Issuer – Litigation and arbitration proceedings”).

Accordingly, the Issuer’s business, financial condition, results of operations or cash flows could be adversely affected by the outcome of one or more of such proceedings. Although the Issuer has taken out insurance policies specifically to cover these risks and has established provisions for the considered most critical disputes and litigations, such insurance coverage and provisions may not be sufficient to cover all of the Issuer’s losses, increased costs or liabilities that may arise, or which the Issuer may incur, as a result of these proceedings.

Acquisitions could have an adverse effect on Terna’s business

Terna may expand its business through acquisitions, which may involve significant risks that could have a material adverse effect on its business, financial condition and operations. Such risks include, but are not limited to, difficulties in the assimilation or integration of the operations, services and corporate culture of the acquired companies, failure to achieve expected synergies, adverse operating issues that Terna fails to discover prior to the acquisition, insufficient indemnification from the selling parties for

legal liabilities incurred by the acquired companies prior to the acquisitions and the incurrence of significant indebtedness.

Indemnification obligations arising from the sale of Rete Rinnovabile S.r.l. and Nuova Rete Solare S.r.l.

Until 18 October 2010, SunTergrid S.p.A., a subsidiary of the Issuer, was the owner of the entire share capital of Rete Rinnovabile S.r.l. which operated in the renewable energy sector and was entrusted with managing, developing and maintaining photovoltaic plants and collecting the incentive tariff as provided by Italian law.

On 31 March 2011 SunTergrid S.p.A., a subsidiary of the Issuer, sold the entire share capital of Rete Rinnovabile S.r.l. which operated in the renewable energy sector and was entrusted with managing, developing and maintaining photovoltaic plants and collecting the incentive tariff as provided by Italian law to RTR Acquisitions S.r.l., (an affiliate of Terra Firma Investments (GP) 3 Limited which was wholly controlled by Terra Firma Capital Partners III, L.P.).

In the course of 2011, SunTergrid S.p.A. carried out a similar transaction concerning its wholly owned company, Nuova Rete Solare S.r.l. which operated in the renewable energy sector and in the managing, developing and maintaining photovoltaic plants.

On 24 October 2011, SunTergrid S.p.A. sold 100 per cent. of the share capital of Nuova Rete Solare S.r.l. to RTR Holding III S.r.l., a subsidiary of Terra Firma.

As a result of the divestments of Rete Rinnovabile S.r.l. and Nuova Rete Solare S.r.l., the Issuer may be required to indemnify and hold harmless the purchasers and other parties involved in the transactions subject to certain circumstances.

In this respect, the Issuer established a provision for contingent liabilities arising from such obligations which, as at 31 December 2020, was Euro 2 million.

Risks related to the internal control of the Issuer

Information and cyber risk

Information and cyber risk of incurring operating losses, market share losses or suffering reputational damage as a result of the use of information and communications technology or as a consequence of cyber attacks.

The Issuer depends on its Information Technology (IT) and Operation Technology (OT and, together with the IT, IT/OT) and data processing systems to operate its business, as well as on their continuous maintenance and constant updating. The Issuer is exposed to the risk that data could be damaged or lost, removed, or disclosed by unauthorised parties and to the risk that business critical IT/OT services could be damaged or compromised from an attacker.

This would have a negative impact on the Issuer’s business and reputation, and could subject the Issuer to fines, with consequent negative effects on its business, results of operations or financial condition.

Risks faced by the Issuer relating to the management of IT systems include possible violations of its systems due to unauthorised access to the corporate network or IT resources, the introduction of viruses into computers or any other form of abuse committed via the Internet. Like attempted hacking, such violations have become more frequent over the years throughout the world and therefore can threaten the protection of information relating to the Issuer and its customers and can have negative effects on

the integrity of the Issuer’s IT systems, as well as on the confidence of the customers and on the Issuer’s reputation, with possible negative effects on the Group’s capital and financial condition.

In order to prevent such risks, Terna has had an Information Security Governance Model, which enables it to identify the most significant cyber risks. For further details please see section “Description of the Issuer – Information and Cyber Security Risk”.

Risks related to the political, environmental, social and governance environment of the issuer.

The interests of the controlling shareholder may differ from those of the other shareholders

The interests of CDP RETI S.p.A. (or any of its shareholders) (hereinafter referred to as CDP RETI), which is the majority shareholder of Terna (~30 per cent.), in any decisions may differ from those of other Issuer’s shareholders and may have an impact on the Issuer’s business decisions.

For a more detailed analysis please refer to the following sections: “Description of the Issuer – Overview”, “Description of the Issuer – History and development”, “Description of the Issuer – Share capital of Terna, major shareholders and related party transactions” and “Description of the Issuer – Share capital of Terna, major shareholders and related party transactions – Limitations on shareholding – Shares granting special powers”.

Risks connected to the effects of the international financial crisis on the Issuer’s business, results of operations and financial condition

In the near future the stability of the European financial system might be adversely impacted also by several events, including those related to the COVID-19 epidemiologic crisis. In any event, the European Central Bank has confirmed its commitment to continue promoting financial stability.

As a result, the Issuer’s ability to access the capital and financial markets and to refinance debt to meet financial requirements of the Issuer and its Group may be adversely impacted and costs of financing may significantly increase. This could materially and adversely affect the Issuer’s business, results of operations and financial condition.

COVID-19

The outbreak during the first half of 2020 of coronavirus disease (COVID-19) was declared a pandemic by the World Health Organization, and the Secretary of Health and Human Services declared a public health emergency in the United States in response to the outbreak; likewise, the Italian Government also declared a state of emergency and passed a number of emergency measures to deal with the outbreak. These included restrictions on travel and the free circulation of people as well as institutional closures, which continued during the second half of 2020 and the beginning of 2021 with “second wave” and “third wave” restrictions. This outbreak (and any future outbreaks) has led (and may continue to lead) to disruptions in the economies of those nations where COVID-19 has arisen and may in the future arise, including Italy, and may result in adverse impacts on the global economy in general.

These circumstances have led to volatility in the capital markets, which may lead to volatility in or disruption of the credit markets at any time and may adversely affect the value of the Notes. The potential impacts, including a global, regional or other economic recession, are increasingly uncertain and difficult to assess. If the spread of COVID-19 persists for a significant period of time, or other measures are put in place, this could have a materially negative impact on the global economy.

Moreover, the outbreak of COVID-19, and the measures taken in relation thereto, will directly or indirectly result in increases of defaults under mortgage loans. Payment holidays have been granted and could be granted again in the future pursuant to emergency legislation to borrowers in distress due to

the COVID-19 outbreak, under which borrowers are allowed to defer making payments for certain periods of time. This may result in payment disruptions and possibly higher losses under the mortgage loans. The impact will strongly depend on the duration and severity of the COVID-19 outbreak.

The Issuer may have to incur significant costs to mitigate the effects of the foregoing. The Issuer's prospects, financial condition and results of operations in particular may be materially affected by the above factors, events and developments. Investors should note the risk that the virus, or any governmental or societal response to the virus, may affect the business activities and financial results of the Issuer and the Group or may impact the functioning of the financial system(s) needed to make regular and timely payments under the Notes, and therefore the ability of the Issuer to make payments on the Notes.

International political and economic developments or terrorist incidents may adversely affect the results of the Issuer

Recent years have been marked by a series of negative geopolitical, economic and financial events. The potential effects of these events on economic growth in Europe may result in lower consumption of electricity by industrial users in Italy, thus adversely affecting the Issuer’s revenues and prospects for growth.

In addition, the events mentioned above may increase the volatility of equity valuations and share/debt trading prices, including the market price of any Notes issued pursuant to the Programme.

Risks connected with the political and economic decisions of EU and Eurozone countries and the United Kingdom leaving the European Union (Brexit)

On 31 January 2020 (exit day), the UK withdrew from the EU. Pursuant to Articles 126 and 127 of the Article 50 Withdrawal Agreement that entered into force on exit day, the UK entered an implementation period during which it negotiated its future relationship with the EU under the political declaration that accompanied the Article 50 Withdrawal Agreement. During such implementation period – which ended at 11 p.m. UK time (midnight CET) on 31 December 2020 (the implementation period completion day, or IP completion day) – EU law generally continued to apply in the UK.

Following such negotiations, on 24 December 2020 the UK and the EU concluded a free trade agreement known as the ‘UK-EU Trade and Cooperation Agreement’ (the TCA). The TCA, which entered into force (initially on a temporary basis) on IP completion day, is principally a free trade agreement in goods. It does not address in any detail a number of areas, including the cross-border provision of services, the ‘passporting’ of UK and EU financial institutions, the determination of equivalence between EU and UK financial market regulations, or judicial cooperation in civil matters. In addition, on IP completion day, as a unilateral matter and in order to mitigate the effect of the EU Treaties no longer applying to the UK, the UK incorporated into its law (i.e. grandfathered) the majority of EU law as it stood at IP completion day (EU retained law).

Notwithstanding the conclusion of the Withdrawal Agreement and the TCA by the EU and the UK, and the implementation by the UK of EU retained law, there remain significant uncertainties with regard to the political and economic outlook of the UK and the EU and there are likely to be changes in the legal rights and obligations of commercial parties across all industries, particularly in the services sector (including financial services) following the UK's exit from the EU.

There is a risk that other EU Member States could hold referenda as to their membership of, and ultimately leave, the EU, as the UK did, and that one or more EU Member States that adopted the Euro as their national currency might decide, in the long term, to adopt an alternative currency, or that there is a prolonged period of uncertainty connected to these eventualities. These risks if they materialised could have a significant negative impact on global economic conditions and the stability of the

international financial markets. This could include further volatility in equity markets, in the value of sterling and/or the Euro and in financial markets generally, a reduction in global market liquidity with a potential negative impact on asset prices, operating results and capital including as may impact the financial position of the Issuer and/or the Group and the market value and/or liquidity of the Notes in the secondary market.

In addition to the above, and in consideration of the fact that at the date of this Base Prospectus there is no legal procedure or practice aimed at facilitating the exit of a Member State from the Eurozone, the consequences of these decisions are exacerbated by the uncertainty regarding the methods by which a Member State could manage its current assets and liabilities denominated in Euros and the exchange rate between the newly adopted currency and the Euro. A collapse of the Eurozone could be accompanied by the deterioration of the economic and financial situation of the European Union and could have a significant negative effect on the entire financial sector, creating new difficulties in the granting of sovereign loans and loans to businesses and involving considerable changes to financial activities both at market and retail level. This situation could therefore have a significant negative impact on the operating results and capital and financial position of the Issuer and/or the Group and/or the Issuer’s ability to pay interest and repay principal under the Notes, as well as the market value and/or the liquidity of the Notes in the secondary market.

The Issuer may incur substantial costs to comply with environmental laws

The activities of the Terna Group are also affected by environmental legislation at National, European and International level, including in relation to electromagnetic fields and landscape.

The Terna Group may incur increased costs due to the implementation of, and compliance with, environmental regulations calling for preventive measures or other requirements.

Furthermore, in the future, the European Union or the Italian Government may adopt stricter laws that would require the Terna Group to upgrade, relocate or make other changes to some of its existing electricity transmission networks and systems and would result in the Terna Group incurring significant expenditures in order to do so. The Issuer cannot ensure that such costs will not arise in the future. These costs may adversely impact the Issuer’s financial performance and results of operations.

Also, local opposition to these required actions could further increase the Terna Group’s costs due to delays in the completion of the necessary upgrades, relocations or any other changes as described above or due to civil action.

The Issuer may be affected by changes in energy laws, tax laws and public sector laws

The activities of the Terna Group (and accordingly, the revenues deriving from such activities) may be affected by changes in the rules governing the electricity market, strategic infrastructures or the authorisation procedures for transmission infrastructures or having an impact on the relationships between the companies of the Terna Group and other stakeholders (producers, distributors, etc.).

More in particular, European institutions have completed in 2019 a new legal framework for the energy union, the so-called “Clean Energy Package” and Terna is working at the European Green Deal, a roadmap that seeks to make the EU the first climate-neutral continent by 2050. As a result, further legislative initiatives at national level are expected in the near future to transpose the EU regulation.

As of the date of this Base Prospectus, the Terna Group cannot predict what effect, if any, such developments may have on its business.

The energy industry is subject to the payment of income taxes which can be higher than those payable in many other commercial activities. In addition, in recent years, the Issuer has experienced adverse

changes in the tax regimes applicable to electricity companies. These companies are not permitted by law to pass on the increased tax liability to customers via a tariff increase and this therefore may result in additional costs for the Issuer.

Any future adverse changes in the income tax rate or other taxes or charges applicable to the Terna Group would have a negative impact on the Issuer’s future results of operations and cash flows.

Employees and key personnel

The Issuer’s ability to operate its business effectively depends on the capabilities and performance of its personnel. Loss of key personnel or an inability to attract, train or retain appropriately qualified personnel (in particular for technical positions where availability of appropriately qualified personnel may be limited) or if significant disputes arise with employees, may affect the Issuer’s ability to implement its long-term business strategy and there may be a material adverse effect on its business, financial condition, results of operations and prospects.

Furthermore, there is a risk that an employee or an individual acting on behalf of the Issuer may breach anti-bribery legislation or otherwise breach the Issuer’s internal controls or internal governance framework. This could impact on the Issuer’s results of operations, its reputation and, as a consequence, its ability to meet its obligations on the Notes.

For further details and the analysis of the polices implemented by the Issuer please see section “Description of the Issuer - Senior Management and Employees”.

FACTORS WHICH ARE MATERIAL FOR THE PURPOSE OF ASSESSING THE MARKET RISKS ASSOCIATED WITH NOTES ISSUED UNDER THE PROGRAMME

The risks below have been classified into the following categories:

– Risks applicable to all Notes;

– Risks related to the structure of a particular issue of Notes;

– Risks applicable to certain types of Exempt Notes;

– Risks related to Notes generally; and

– Risks related to the Market Generally.

Risks applicable to all Notes

If the Issuer has the right to redeem any Notes at its option, this may limit the market value of the Notes concerned and an investor may not be able to reinvest the redemption proceeds in a manner which achieves a similar effective return.

An optional redemption feature is likely to limit the market value of Notes. During any period when the Issuer may elect to redeem Notes, the market value of those Notes generally will not rise substantially above the price at which they can be redeemed. This may also be true prior to any redemption period.

The Issuer may be expected to redeem Notes when its cost of borrowing is lower than the interest rate on the Notes. At those times, an investor generally will not be able to reinvest the redemption proceeds at an effective interest rate as high as the interest rate on the Notes being redeemed, and may only be able to do so at a significantly lower rate. Potential investors should consider the risk of reinvestment in light of other investments available at that time.

In addition, with respect to Condition (7.5) (Redemption at the option of the Issuer (Clean-Up Call)), there is no obligation under the Condition for the Issuer to inform investors if and when 80 per cent. of the initial aggregate principal amount of the Notes has been purchased and cancelled, and the Issuer’s right to redeem will exist notwithstanding that immediately prior to the serving of a notice in respect of the exercise of the Clean-Up Call, the Notes may have been trading significantly above par, thus potentially resulting in a loss of capital invested.

If the Notes include a feature to convert the interest basis from a fixed rate to a floating rate, or vice versa, this may affect the secondary market and the market value of the Notes concerned.

Fixed/Floating Rate Notes are Notes which bear interest at a rate that converts from a fixed rate to a floating rate, or from a floating rate to a fixed rate. Such a feature to convert the interest basis, and any conversion of the interest basis, may affect the secondary market in, and the market value of, such Notes as the change of interest basis may result in a lower interest return for Noteholders. Where the Notes convert from a fixed rate to a floating rate, the spread on the Fixed/Floating Rate Notes may be less favourable than then prevailing spreads on comparable Floating Rate Notes tied to the same reference rate. In addition, the new floating rate at any time may be lower than the rates on other Notes. Where the Notes convert from a floating rate to a fixed rate, the fixed rate may be lower than then prevailing rates on those Notes and could affect the market value of an investment in the relevant Notes.

Notes which are issued at a substantial discount or premium may experience price volatility in response to changes in market interest rates.

The market values of securities issued at a substantial discount (such as Zero Coupon Notes) or premium to their principal amount tend to fluctuate more in relation to general changes in interest rates than do prices for more conventional interest-bearing securities. Generally, the longer the remaining term of such securities, the greater the price volatility as compared to more conventional interest-bearing securities with comparable maturities.

Risks related to the structure of a particular issue of Notes

A wide range of Notes may be issued under the Programme. A number of these Notes may have features which contain particular risks for potential investors. Set out below is a description of the most common such features, distinguishing between factors which may occur in relation to any Notes and those which might occur in relation to certain types of Exempt Notes:

Risks relating to Inflation Linked Notes

The Issuer may issue Inflation Linked Notes (being either an Inflation Linked Interest Note, an Inflation Linked Redemption Note or a combination of the two) where the amount of principal and/or interest or the settlement amount payable are dependent upon the level of an inflation/consumer price index or indices.

Potential investors in any such Notes should be aware that depending on the terms of the Inflation Linked Notes (i) they may receive no interest or a limited amount of interest, (ii) payment of principal, interest or the settlement amount may occur at a different time than expected and (iii) they may lose a substantial portion of their investment. In addition, the movements in the level of the inflation/consumer price index or indices may be subject to significant fluctuations that may not correlate with changes in interest rates, currencies or other indices and the timing of changes in the relevant level of the index or indices may affect the actual return to investors, even if the average level is consistent with their expectations.

Inflation Linked Notes may be subject to certain disruption provisions or extraordinary event provisions. Relevant events may relate to an inflation/consumer price index publication being delayed

or ceasing or such index being rebased or modified. If the Calculation Agent (as defined in the Conditions) determines that any such event has occurred this may delay valuations under, and/or settlements in respect of, the Notes and consequently adversely affect the value of the Notes. Any such adjustments may be by reference to a Related Bond, as defined in the applicable Final Terms or Pricing Supplement, as the case may be if so specified therein. In addition certain extraordinary or disruption events may lead to early termination of the Notes which may have an adverse effect on the value of the Notes. Whether and how such provisions apply to the relevant Notes can be ascertained by reading the Inflation Linked Notes Conditions in conjunction with the applicable Final Terms or Pricing Supplement, as the case may be.

If the amount of principal and/or interest or the settlement amount payable are determined in conjunction with a multiplier greater than one or by reference to some other leverage factor, the effect of changes in the level of the inflation/consumer price index or the indices on principal or interest payable will be magnified.

A relevant consumer price index or other formula linked to a measure of inflation to which the Notes are linked may be subject to significant fluctuations that may not correlate with other indices. Any movement in the level of the index may result in a reduction of the interest payable on the Notes (if applicable) or, in the case of Notes with a redemption amount or settlement amount linked to inflation, in a reduction of the amount payable on redemption or settlement which in some cases could be less than the amount originally invested.

The timing of changes in the relevant consumer price index or other formula linked to the measure of inflation comprising the relevant index or indices may affect the actual yield to investors on the Notes, even if the average level is consistent with their expectations.

An inflation or consumer price index to which interest payments and/or the redemption amount or settlement amount of Inflation Linked Notes are linked is only one measure of inflation for the relevant jurisdiction or area, and such Index may not correlate perfectly with the rate of inflation experienced by Noteholders in such jurisdiction or area.

The market price of Inflation Linked Notes may be volatile and may depend on the time remaining to the maturity date or expiration and the volatility of the level of the inflation or consumer price index or indices. The level of the inflation or consumer price index or indices may be affected by the economic, financial and political events in one or more jurisdictions or areas.

In respect of the Notes issued as “Green Bonds”, there can be no assurance that such use of proceeds will be suitable for the investment criteria of an investor

The Issuer’s intention is to allocate the net proceeds from the issue of Notes issued as “Green Bonds” to the financing and/or refinancing of the Eligible Green Projects which meet the Eligibility Criteria (such terms as defined in the “Use of Proceeds” section). Prospective investors should determine for themselves the relevance of such information for the purpose of any investment in such Notes, together with any other investigation such investor deems necessary. In particular, no assurance is given that the use of such net proceeds for any Eligibl e Green Projects will satisfy, whether in whole or in part, any present or future investor expectations or requirements as regards any investment criteria or guidelines with which such investor or its investments are required to comply, whether by any present or future applicable law or regulations (including, amongst others, Regulation (EU) 2020/852 on the establishment of a framework to facilitate sustainable investment (the EU Taxonomy) and the EU Taxanomy Climate Delegated Act adopted by the EU Commision on 21 April 2021 (jointly, the EU Taxonomy Regulation) or by its own by-laws or other governing rules or investment portfolio mandates, in particular with regard to any direct or indirect environmental, sustainability or social impact of any projects or uses, the subject of or related to, any Eligible Green Projects. Furthermore, it

should be noted that there is currently no clearly defined definition (legal, regulatory or otherwise) of, nor market consensus as to what constitutes, a “green” or “sustainable” or an equivalently-labelled project or as to what precise attributes are required for a particular project to be defined as “green” or “sustainable” or such other equivalent label nor can any assurance be given that such a clear definition or consensus will develop over time or that any prevailing market consensus will not significantly change. The EU Taxonomy Regulation establishes a basis for the determination of such a definition in the EU. However, the EU Taxonomy remains subject to the implementation of delegated regulations by the European Commission on technical screening criteria for the environmental objectives set out in the EU Taxonomy Regulation. Accordingly, no assurance is or can be given to investors that any projects or uses which are the subject of, or related to, any Eligible Green Projects will meet any or all investor expectations regarding such “green”, “sustainable” or other equivalently-labelled performance objectives or that any adverse environmental, social and/or other impacts will not occur during the implementation of any projects or uses which are the subject of, or related to, any Eligible Green Projects.

No assurance or representation is given as to the suitability or reliability for any purpose whatsoever of any opinion, report or certification of any third party (whether or not solicited by the Issuer) which may be made available in connection with the issue of the Notes and in particular with any Eligible Green Projects to fulfil any environmental, sustainability, social and/or other criteria. For the avoidance of doubt, any such opinion, report or certification is not, nor shall be deemed to be, incorporated in to and/or form part of the Base Prospectus. Any such opinion, report or certification is not, nor should be deemed to be, a recommendation by the Issuer or any other person to buy, sell or hold the Notes. Any such opinion, report or certification is only current as of the date that opinion was initially issued. Prospective investors must determine for themselves the relevance of any such opinion, report or certification and/or the information contained therein and/or the provider of such opinion, report or certification for the purpose of any investment in the Notes. Currently, the providers of such opinions, report and certifications are not subject to any specific regulatory or other regime or oversight.

In the event that any such Notes are listed or admitted to trading on any dedicated “green”, “environmental”, “sustainable” or other equivalently-labelled segment of any stock exchange or securities market (whether or not regulated), no representation or assurance is given by the Issuer or any other person that such listing or admission satisfies, whether in whole or in part, any present or future investor expectations or requirements as regards any investment criteria or guidelines with which such investor or its investments are required to comply, whether by any present or future applicable law or regulations or by its own by-laws or other governing rules or investment portfolio mandates, in particular with regard to any direct or indirect environmental, sustainability or social impact of any projects or uses, the subject of or related to, any Eligible Green Projects. Furthermore, it should be noted that the criteria for any such listings or admission to trading may vary from one stock exchange or securities market to another. Nor is any representation or assurance given or made by the Issuer or any other person that any such listing or admission to trading will be obtained in respect of any such Notes or, if obtained, that any such listing or admission to trading will be maintained during the life of the Notes.

While it is the intention of the Issuer to apply the net proceeds of Notes issued as “Green Bonds” so specified for Eligible Green Projects in, or substantially in, the manner described in the Base Prospectus, there can be no assurance that the relevant project(s) or use(s) the subject of, or related to, any Eligible Green Projects will be capable of being implemented in or substantially in such a manner and/or accordance with any timing schedule and that accordingly such proceeds will be totally or partially disbursed for such Eligible Green Projects. Nor can there be any assurance that such Eligible Green Projects will be completed within any specified period or at all or with the results or outcome (whether or not related to the environment) as originally expected or anticipated by the Issuer. Any such event or failure by the Issuer will not constitute an Event of Default under the Notes.

Any such event or failure to apply the proceeds of any issue of Notes for any Eligible Green Projects as aforesaid and/or withdrawal of any such opinion or certification or any such opinion or certification attesting that the Issuer is not complying in whole or in part with any matters for which such opinion or certification is opining or certifying on and/or any such Notes no longer being listed or admitted to trading on any stock exchange or securities market as aforesaid may have a material adverse effect on the value of such Notes and also potentially the value of any other Notes which are intended to finance Eligible Green Projects and/or result in adverse consequences for certain investors with portfolio mandates to invest in securities to be used for a particular purpose.

No Dealer makes any representation as to the suitability of the Notes to fulfil environmental and sustainability criteria required by prospective investors. The Dealers have not undertaken, nor are responsible for, any assessment of the Eligibility Criteria, any verification of whether the Eligible Green Projects meet the Eligibility Criteria, or the monitoring of the use of proceeds. Investors should refer to the Issuer’s website (www.terna.it), the green bond framework of the Issuer and the second party opinion for information. The second party opinion provider has been appointed by the Issuer. The second party opinion and the green bond framework will be made available on the Issuer's website (www.terna.it).

Step Up Notes (Sustainability-linked Bonds) may not be a suitable investment for all investors seeking exposure to assets with sustainability characteristics

Although the interest rate relating to the Step Up Notes is subject to upward adjustment in certain circumstances specified in the Conditions, such Notes may not satisfy an investor's requirements or any future legal or quasi legal standards for investment in assets with sustainability characteristics. Step Up Notes are not being marketed as green bonds since the Issuer expects to use the relevant net proceeds for general corporate purposes and therefore the Issuer does not intend to allocate the net proceeds specifically to projects or business activities meeting environmental or sustainability criteria, or be subject to any other limitations associated with green bonds.

In addition, the interest rate adjustment in respect of Step Up Notes depends on a definition of Absolute Scope 1 and 2 GHG Emissions that may be inconsistent with investor requirements or expectations or other definitions relevant to greenhouse gas emissions. The Issuer defines Absolute Scope 1 and 2 GHG Emissions as the release of GHG into the atmosphere, related to Scope 1 and Scope 2 and reported in the form of amount of emissions in metric tonnes of CO2eq.

The issuer has so far annually disclosed Absolute Scope 1 and 2 GHG Emissions in accordance with GRI standards’ requirements. The Group’s Non-Financial Disclosure is subject of third-party verification in compliance with the criteria established in the “International Standard on Assurance Engagements ISAE 3000 (Revised) – Assurance Engagements Other than Audits or Reviews of Historical Financial Information” issued by the International Auditing and Assurance Standards Board (IAASB) for limited assurance engagements.

Furthermore, any information on, or accessible through, the Issuer’s website and the information in such certifications or reports or any past or future reports, certifications, opinions, Limited Assurance Reports and/or External Verifier Assurance Reports is not part of the Base Prospectus and should not be relied upon in connection with making any investment decision with respect to any Notes to be issued under the Programme.

Although the Issuer targets decreasing its direct greenhouse gas emissions, there can be no assurance of the extent to which it will be successful in doing so or that any future investments it makes in furtherance of this target will meet investor expectations or any binding or non-binding legal standards regarding sustainability performance, whether by any present or future applicable law or regulations or by its own by-laws or other governing rules or investment portfolio mandates, in particular with regard

to any direct or indirect environmental, sustainability or social impact. Adverse environmental or social impacts may occur during the design, construction and operation of any investments the Issuer makes in furtherance of these targets or such investments may become controversial or criticized by activist groups or other stakeholders. An Absolute Scope 1 and 2 GHG Emissions Event shall not occur in the case of the failure of the Issuer to satisfy the Absolute Scope 1 and 2 GHG Emissions Condition as a result of certain events described in the Conditions. Lastly, no Event of Default shall occur under the Step Up Notes, nor will the Issuer be required to repurchase or redeem such Notes, if the Issuer fails to reach its Absolute Scope 1 and 2 GHG Emissions.

A portion of Terna Group's indebtedness may include certain triggers linked to sustainability key performance indicators

A portion of Terna Group's indebtedness may include certain triggers linked to sustainability key performance indicators such as total greenhouse gas emissions (see "Step Up Notes (Sustainability- linked Bonds) may not be a suitable investment for all investors seeking exposure to assets with sustainability characteristics") which must be complied with by the Issuer, and in respect of which a Step Up Option applies if specified as being applicable in the relevant Final Terms. The failure to meet such sustainability key performance indicators will result in increased interest amounts under such Notes, which would increase Terna Group's cost of funding and which could have a material adverse effect on Terna Group, its business prospects, its financial condition or its results of operations.

Risks applicable to certain types of Exempt Notes

There are particular risks associated with an investment in certain types of Exempt Notes, such as Index Linked Notes and Dual Currency Notes. In particular, an investor might receive less interest than expected or no interest in respect of such Notes and may lose some or all of the principal amount invested by it.

The Issuer may issue Notes with principal or interest determined by reference to an index or formula, to changes in the prices of securities or commodities, to movements in currency exchange rates or to other factors (each, a Relevant Factor). In addition, the Issuer may issue Notes with principal or interest payable in one or more currencies which may be different from the currency in which the Notes are denominated. Potential investors should be aware that:

(i) the market price of such Notes may be volatile;

(ii) they may receive no interest;

(iii) payment of principal or interest may occur at a different time or in a different currency than expected;

(iv) they may lose all or a substantial portion of their principal;

(v) a Relevant Factor may be subject to significant fluctuations that may not correlate with changes in interest rates, currencies or other indices;

(vi) if a Relevant Factor is applied to Notes in conjunction with a multiplier greater than one or contains some other leverage factor, the effect of changes in the Relevant Factor on principal or interest payable is likely to be magnified; and

(vii) the timing of changes in a Relevant Factor may affect the actual yield to investors, even if the average level is consistent with their expectations. In general, the earlier the change in the Relevant Factor, the greater the effect on yield.

The historical experience of an index or other Relevant Factor should not be viewed as an indication of the future performance of such Relevant Factor during the term of any Notes. Accordingly, each potential investor should consult its own financial and legal advisers about the risk entailed by an investment in any Notes linked to a Relevant Factor and the suitability of such Notes in light of its particular circumstances.

Where Notes are issued on a partly paid basis, an investor who fails to pay any subsequent instalment of the issue price could lose all of his investment.

The Issuer may issue Notes where the issue price is payable in more than one instalment. Any failure by an investor to pay any subsequent instalment of the issue price in respect of his Notes could result in such investor losing all of his investment.

Notes which are issued with variable interest rates or which are structured to include a multiplier or other leverage factor are likely to have more volatile market values than more standard securities.

Notes with variable interest rates can be volatile investments. If they are structured to include multipliers or other leverage factors, or caps or floors, or any combination of those features or other similar related features, their market values may be even more volatile than those of securities that do not include those features.

The value of Fixed Rate Notes may be adversely affected by movements in market interest rates

Investment in Fixed Rate Notes involves the risk that if market interest rates subsequently increase above the rate paid on the Fixed Rate Notes, this will adversely affect the value of the Fixed Rate Notes.

Risks related to Notes generally

Set out below is a description of material risks relating to the Notes generally:

The Conditions contain provisions which may permit their modification without the consent of all investors and confer significant discretions on the Trustee which may be exercised without the consent of the Noteholders and without regard to the individual interests of particular Noteholders.

The Conditions contain provisions for calling meetings of Noteholders to consider and vote upon matters affecting their interests generally, or to pass resolutions in writing or through the use of electronic consents. These provisions permit defined majorities to bind all Noteholders, including Noteholders who did not attend or vote at the relevant meeting or, as the case may be, did not sign the written resolution or give their consent electronically, and including those Noteholders who voted against the majority.

As provided under article 2415, first paragraph, number 2, of the Italian Civil Code, the Noteholders may, by an Extraordinary Resolution passed by a specific majority, modify the Conditions (these modifications may relate to, without limitation, the maturity of the Notes or the dates on which interest is payable on them; the principal amount of, or interest on, the Notes; or the currency of payment of the Notes). These and other changes to the Conditions of the Notes may adversely impact Noteholders’ rights and may adversely impact the market value of the Notes.

The Conditions also provide that the Trustee may, without the consent of Noteholders and without regard to the interests of particular Noteholders, agree to (i) any modification of, or the waiver or authorisation of any breach or proposed breach of, any of the provisions of the Notes or (ii) determine without the consent of the Noteholders that any Event of Default or potential Event of Default shall not

be treated as such, in the circumstances described in Condition 10 (Events of Default and Enforcement), including in respect of any amendment to the Notes.

The Notes may be subject to withholding taxes in circumstances where the Issuer is not obliged to make gross up payments and this would result in holders receiving less interest than expected and could significantly adversely affect their return on the Notes.

U.S. Dividend Equivalent Withholding

Section 871(m) of the U.S. Internal Revenue Code of 1986 (the Code) causes a 30 per cent. withholding tax on amounts attributable to U.S. source dividends that are paid or "deemed paid" under certain financial instruments if certain conditions are met (such instruments, Specified Securities). If the Issuer or any withholding agent determines that withholding is required, neither the Issuer nor such withholding agent will be required to pay any additional amounts with respect to amounts so withheld. Prospective investors should refer to the section "Taxation – U.S. Dividend Equivalent Withholding".

For purposes of withholding under the U.S. Foreign Account Tax Compliance Act, commonly known as FATCA, Specified Securities are subject to a different grandfathering rule than other Notes. Prospective investors should refer to the section “Taxation – Foreign Account Tax Compliance ACT”.

The value of the Notes could be adversely affected by a possible judicial decision, a change in English law or administrative practice

The Conditions are based on English law in effect as at the date of this Base Prospectus. No assurance can be given as to the impact of any possible judicial decision or change in English law or administrative practice after the date of this Base Prospectus and any such change could materially adversely impact the value of any Notes affected by it.

Investors who purchase Notes in denominations that are not an integral multiple of the Specified Denomination may be adversely affected if definitive Notes are subsequently required to be issued

In relation to any issue of Notes which have denominations consisting of a minimum Specified Denomination plus one or more higher integral multiples of another smaller amount, it is possible that such Notes may be traded in amounts in excess of the minimum Specified Denomination that are not integral multiples of such minimum Specified Denomination. In such a case a holder who, as a result of trading such amounts, holds an amount which is less than the minimum Specified Denomination in his account with the relevant clearing system at the relevant time may not receive a definitive Note in respect of such holding (should definitive Notes be printed) and would need to purchase a principal amount of Notes such that its holding amounts to a Specified Denomination.

If such Notes in definitive form are issued, holders should be aware that definitive Notes which have a denomination that is not an integral multiple of the minimum Specified Denomination may be illiquid and difficult to trade.

Trading in the clearing systems

In relation to any issue of Notes which have a minimum denomination and are tradable in the clearing systems in amounts above such minimum denomination which are smaller than it, should definitive Notes be required to be issued, a holder who does not have an integral multiple of the minimum denomination in his account with the relevant clearing system at the relevant time may not receive all of his entitlement in the form of definitive Notes unless and until such time as his holding becomes an integral multiple of the minimum denomination.

The regulation and reform of “benchmarks” may adversely affect the value of Notes linked to or referencing such “benchmarks”

Interest rates and indices which are deemed to be “benchmarks”, are the subject of recent national and international regulatory guidance and proposals for reform. Some of these reforms are already effective whilst others are still to be implemented. These reforms may cause such benchmarks to perform differently than in the past, to disappear entirely, or have other consequences which cannot be predicted. Any such consequence could have a material adverse effect on any Notes referencing such a “benchmark”, such as Floating Rate Notes.

The EU Benchmarks Regulation applies to the provision of benchmarks, the contribution of input data to a benchmark and the use of a benchmark within the EU. It, among other things, (i) requires benchmark administrators to be authorised or registered (or, if non-EU-based, to be subject to an equivalent regime or otherwise recognised or endorsed) and (ii) prevents certain uses by EU supervised entities of “benchmarks” of administrators that are not authorised or registered (or, if non-EU based, not deemed equivalent or recognised or endorsed). Regulation (EU) 2016/1011 as it forms part of domestic law by virtue of the EUWA (the UK Benchmarks Regulation) among other things, applies to the provision of benchmarks and the use of a benchmark in the UK. Similarly, it prohibits the use in the UK by UK supervised entities of benchmarks of administrators that are not authorised by the FCA or registered on the Financial Conduct Authority (FCA) register (or, if non-UK based, not deemed equivalent or recognised or endorsed).

The EU Benchmarks Regulation and/or the UK Benchmarks Regulation, as applicable, could have a material impact on any Notes linked to a rate or index deemed to be a “benchmark”, including any Floating Rate Notes linked to or referencing LIBOR and/or EURIBOR, in particular, if the methodology or other terms of the “benchmark” are changed in order to comply with the requirements of the EU Benchmarks Regulation and/or the UK Benchmarks Regulation, as applicable. Such changes could, among other things, have the effect of reducing, increasing or otherwise affecting the volatility of the published rate or level of the benchmark.

More broadly, any of the international or national reforms, or the general increased regulatory scrutiny of “benchmarks”, could increase the costs and risks of administering or otherwise participating in the setting of a “benchmark” and complying with any such regulations or requirements.

Specifically, the sustainability of LIBOR has been questioned as a result of the absence of relevant active underlying markets and possible disincentives (including possibly as a result of benchmark reforms) for market participants to continue contributing to such benchmarks. The FCA has indicated through a series of announcements that the continuation of LIBOR on the current basis cannot and will not be guaranteed after 2021. On 5 March 2021, ICE Benchmark Administration Limited (IBA), the administrator of LIBOR, published a statement confirming its intention to cease publication of all LIBOR settings, together with the dates on which this will occur, subject to the FCA exercising its powers to require IBA to continue publishing such LIBOR settings using a changed methodology (the IBA announcement). Concurrently, the FCA published a statement on the future cessation and loss of representativeness of all LIBOR currencies and tenors, following the dates on which IBA has indicated it will cease publication (the FCA announcement). Permanent cessation will occur immediately after 31 December 2021 for all Euro and Swiss Franc LIBOR tenors and certain Sterling, Japanese Yen and US Dollar LIBOR settings and immediately after 30th June 2023 for certain other USD LIBOR settings. In relation to the remaining LIBOR settings (1-month, 3-month and 6-month Sterling, US Dollar and Japanese Yen LIBOR settings), the FCA will consult on, or continue to consider the case for, using its powers to require IBA to continue their publication under a changed methodology for a further period after end-2021 (end-June 2023 in the case of US Dollar LIBOR). The FCA announcement states that consequently, these LIBOR settings will no longer be representative of the underlying market that such settings are intended to measure immediately after 31 December 2021, in the case of the Sterling and

Japanese Yen LIBOR settings and immediately after 30 June 2023, in the case of the USD LIBOR settings. Any continued publication of the Japanese Yen LIBOR settings will also cease permanently at the end of 2022.

Separately, the euro risk free-rate working group for the euro area has published a set of guiding principles and high level recommendations for fallback provisions in, among other things, new euro denominated cash products (including bonds) referencing EURIBOR. The guiding principles indicate, among other things, that continuing to reference EURIBOR in relevant contracts (without robust fallback provisions) may increase the risk to the euro area financial system. On 25 November 2020, the euro risk-free rate working group published consultations on EURIBOR fallback trigger events and fallback rates. The final recommendations are expected to be published during the second quarter of 2021.

Such factors may have the following effects on certain “benchmarks”: (i) discourage market participants from continuing to administer or contribute to the “benchmark”; (ii) trigger changes in the rules or methodologies used in the “benchmark”; or (iii) lead to the disappearance of the “benchmark”. Any of the above changes or any other consequential changes as a result of international or national reforms or other initiatives or investigations, could have a material adverse effect on the value of and return on any Notes linked to or referencing a “benchmark”.

Investors should be aware that, if an Original Reference Rate were discontinued or otherwise unavailable, the rate of interest on Floating Rate Notes which reference such Original Reference Rate will be determined for the relevant period by the fall-back provisions applicable to such Notes. Depending on the manner in which the relevant Original Reference Rate is to be determined under the Conditions, this may in certain circumstances result in (i) if ISDA Determination applies, the application of a backward-looking, risk-free overnight rate, whereas the Original Reference Rate is expressed on the basis of a forward-looking term and includes a risk-element based on inter-bank lending, or (ii) if Screen Rate Determination applies, the effective application of a fixed rate based on the rate which applied in the previous period when the relevant Original Reference Rate was available. Any of the foregoing could have an adverse effect on the value or liquidity of, and return on, any Floating Rate Notes which reference the relevant Original Reference Rate.

The Conditions provide for certain fallback arrangements in the event that a published benchmark (including any page on which such benchmark may be published (or any successor service)) becomes unavailable or a Benchmark Event (as defined in the Conditions) otherwise occurs, including the possibility that the rate of interest could be set by reference to a Successor Rate or an Alternative Rate determined by an Independent Adviser in consultation with the Issuer and that such Successor Rate or Alternative Rate may be adjusted (if required) in order to reduce or eliminate, to the extent reasonably practicable in the circumstances, any economic prejudice or benefit (as applicable) to investors arising out of the replacement of the relevant benchmark. The application of a Successor Rate or an Alternative Rate or an Adjustment Spread may result in the relevant Notes performing differently (which may include payment of a lower interest rate) than they would do if the relevant Original Reference Rate were to continue to apply in its current form. If no Adjustment Spread is determined, a Successor Rate or Alternative Rate may nonetheless be used to determine the rate of interest. In certain circumstances the ultimate fallback of interest for a particular Interest Period may result in the rate of interest for the last preceding Interest Period being used. This may result in the effective application of a fixed rate for Floating Rate Notes based on the rate which was last observed on the Relevant Screen Page. In addition, due to the uncertainty concerning the availability of Successor Rates and Alternative Rates and the involvement of an Independent Adviser, the relevant fallback provisions may not operate as intended at the relevant time.

Any such consequences could have an adverse effect on the value of and return on any such Notes. Moreover, any of the above matters or any other significant change to the setting or existence of any

relevant reference rate could affect the ability of the Issuer to meet its obligations under the Floating Rate Notes or could have a material adverse effect on the value or liquidity of, and the amount payable under, the Floating Rate Notes. Investors should consider these matters with their own independent advisers when making their investment decision with respect to any Floating Rate Notes linked to or referencing a benchmark.

Risks related to the Market Generally

Set out below is a description of material market risks, including liquidity risk, exchange rate risk, interest rate risk and credit risk:

An active secondary market in respect of the Notes may never be established or may be illiquid and this would adversely affect the value at which an investor could sell his Notes

Notes may have no established trading market when issued, and one may never develop. If a market for the Notes does develop, it may not be very liquid. Therefore, investors may not be able to sell their Notes easily or at prices that will provide them with a yield comparable to similar investments that have a developed secondary market. This is particularly the case for Notes that are especially sensitive to interest rate, currency or market risks, are designed for specific investment objectives or strategies or have been structured to meet the investment requirements of limited categories of investors. These types of Notes generally would have a more limited secondary market and more price volatility than conventional debt securities.

If an investor holds Notes which are not denominated in the investor’s home currency, he will be exposed to movements in exchange rates adversely affecting the value of his holding. In addition, the imposition of exchange controls in relation to any Notes could result in an investor not receiving payments on those Notes.

The Issuer will pay principal and interest on the Notes in the Specified Currency. This presents certain risks relating to currency conversions if an investor’s financial activities are denominated principally in a currency or currency unit (hereinafter referred to as the Investor’s Currency) other than the Specified Currency. These include the risk that exchange rates may significantly change (including changes due to devaluation of the Specified Currency or revaluation of the Investor’s Currency) and the risk that authorities with jurisdiction over the Investor’s Currency may impose or modify exchange controls. An appreciation in the value of the Investor’s Currency relative to the Specified Currency would decrease (i) the Investor’s Currency-equivalent yield on the Notes, (ii) the Investor’s Currency-equivalent value of the principal payable on the Notes and (iii) the Investor’s Currency-equivalent market value of the Notes.

Government and monetary authorities may impose (as some have done in the past) exchange controls that could adversely affect an applicable exchange rate or the ability of the Issuer to make payments in respect of the Notes. As a result, investors may receive less interest or principal than expected, or no interest or principal.

Credit ratings assigned to the Issuer or any Notes may not reflect all the risks associated with an investment in those Notes

One or more independent credit rating agencies may assign credit ratings to the Issuer or the Notes. The ratings may not reflect the potential impact of all risks related to structure, market, additional factors discussed above, and other factors that may affect the value of the Notes. A credit rating is not a recommendation to buy, sell or hold securities and may be revised, suspended or withdrawn by the rating agency at any time.

In general, European regulated investors are restricted under the CRA Regulation from using credit ratings for regulatory purposes in the EEA, unless such ratings are issued by a credit rating agency

established in the EEA and registered under the CRA Regulation (and such registration has not been withdrawn or suspended), subject to transitional provisions that apply in certain circumstances. Such general restriction will also apply in the case of credit ratings issued by third country non-EEA credit rating agencies, unless the relevant credit ratings are endorsed by an EEA-registered credit rating agency or the relevant third country rating agency is certified in accordance with the CRA Regulation (and such endorsement action or certification, as the case may be, has not been withdrawn or suspended, subject to transitional provisions that apply in certain circumstances). The list of registered and certified rating agencies published by the European Securities and Markets Authority (ESMA) on its website in accordance with the CRA Regulation is not conclusive evidence of the status of the relevant rating agency included in such list, as there may be delays between certain supervisory measures being taken against a relevant rating agency and the publication of the updated ESMA list.

Investors regulated in the UK are subject to similar restrictions under the UK CRA Regulation. As such, UK regulated investors are required to use for UK regulatory purposes ratings issued by a credit rating agency established in the UK and registered under the UK CRA Regulation. In the case of ratings issued by third country non-UK credit rating agencies, third country credit ratings can either be: (a) endorsed by a UK registered credit rating agency; or (b) issued by a third country credit rating agency that is certified in accordance with the UK CRA Regulation. Note this is subject, in each case, to (a) the relevant UK registration, certification or endorsement, as the case may be, not having been withdrawn or suspended, and (b) transitional provisions that apply in certain circumstances. In the case of third country ratings, for a certain limited period of time, transitional relief accommodates continued use for regulatory purposes in the UK, of existing pre-2021 ratings, provided the relevant conditions are satisfied.

If the status of the rating agency rating the Notes changes for the purposes of the CRA Regulation or the UK CRA Regulation, relevant regulated investors may no longer be able to use the rating for regulatory purposes in the EEA or the UK, as applicable, and the Notes may have a different regulatory treatment, which may impact the value of the Notes and their liquidity in the secondary market. Certain information with respect to the credit rating agencies and ratings is set out on the cover of this Base Prospectus.

Legal investment considerations may restrict certain investments

The investment activities of certain investors are subject to legal investment laws and regulations, or review or regulation by certain authorities. Each potential investor should consult its legal advisers to determine whether and to what extent (i) Notes are legal investments for it, (ii) Notes can be used as collateral for various types of borrowing and (iii) other restrictions apply to its purchase or pledge of any Notes. Financial institutions should consult their legal advisers or the appropriate regulators to determine the appropriate treatment of Notes under any applicable risk-based capital or similar rules.

Potential conflicts of interest with the Calculation Agent

Potential conflicts of interest may exist between the Calculation Agent (if any) and Noteholders (including where a Dealer acts as a calculation agent), including with respect to certain determinations and judgments that such Calculation Agent may make pursuant to the Conditions that may influence amounts receivable by the Noteholders during the term of the Notes and upon their redemption.

The documents incorporated by reference in the Base Prospectus dated 8 June 2020 prepared by the Issuer in connection with the Programme are not incorporated by reference in the Base Prospectus because these are not considered to be relevant for investors.

Any non-incorporated parts of a document referred to herein (which, for the avoidance of doubt, means any parts not listed in the cross-reference list above) are either deemed not relevant for an investor or are otherwise covered elsewhere in this Base Prospectus.

FORM OF THE NOTES

Any reference in this section to “applicable Final Terms” shall be deemed to include a reference to “applicable Pricing Supplement” where relevant.

Each Tranche of Notes will be in bearer form and will initially be issued in the form of a temporary global note (a Temporary Global Note) or, if so specified in the applicable Final Terms, a permanent global note (a Permanent Global Note and, together with a Temporary Global Note, each a Global Note) which, in either case, will:

(a) if the Global Notes are intended to be issued in new global note (NGN) form, as stated in the applicable Final Terms, be delivered on or prior to the original issue date of the Tranche to a common safekeeper (the Common Safekeeper) for Euroclear Bank SA/NV (Euroclear) and Clearstream Banking, S.A. (Clearstream, Luxembourg); and

(b) if the Global Notes are not intended to be issued in NGN Form, be delivered on or prior to the original issue date of the Tranche to a common depositary (the Common Depositary) for Euroclear and Clearstream, Luxembourg.

Where the Global Notes issued in respect of any Tranche are in NGN form, the applicable Final Terms will also indicate whether or not such Global Notes are intended to be held in a manner which would allow Eurosystem eligibility. Any indication that the Global Notes are to be so held does not necessarily mean that the Notes of the relevant Tranche will be recognised as eligible collateral for Eurosystem monetary policy and intra-day credit operations by the Eurosystem either upon issue or at any times during their life as such recognition depends upon satisfaction of the Eurosystem eligibility criteria. The Common Safekeeper for NGNs will either be Euroclear or Clearstream, Luxembourg or another entity approved by Euroclear and Clearstream, Luxembourg.

Whilst any Note is represented by a Temporary Global Note, payments of principal, interest (if any) and any other amount payable in respect of the Notes due prior to the Exchange Date (as defined below) will be made (against presentation of the Temporary Global Note if the Temporary Global Note is not intended to be issued in NGN form) only to the extent that certification (in a form to be provided) to the effect that the beneficial owners of interests in the Temporary Global Note are not U.S. persons or persons who have purchased for resale to any U.S. person, as required by U.S. Treasury regulations, has been received by Euroclear and/or Clearstream, Luxembourg, and Euroclear and/or Clearstream, Luxembourg, as applicable, has given a like certification (based on the certifications it has received) to the Principal Paying Agent (as defined under “Terms and Conditions of the Notes”).

On and after the date (the Exchange Date) which is 40 days after a Temporary Global Note is issued, interests in such Temporary Global Note will be exchangeable (free of charge) upon a request as described therein either (i) for interests in a Permanent Global Note of the same Series or (ii) for definitive Notes of the same Series with, where applicable, receipts, interest coupons and talons attached (as indicated in the applicable Final Terms), in each case against certification of beneficial ownership as described above unless such certification has already been given. The holder of a Temporary Global Note will not be entitled to collect any payment of interest, principal or other amount due on or after the Exchange Date unless, upon due certification, exchange of the Temporary Global Note for an interest in a Permanent Global Note or for definitive Notes is improperly withheld or refused.

Payments of principal, interest (if any) or any other amounts on a Permanent Global Note will be made through Euroclear and/or Clearstream, Luxembourg (against presentation or surrender (as the case may be) of the Permanent Global Note if the Permanent Global Note is not intended to be issued in NGN form) without any requirement for certification.

The applicable Final Terms will specify that a Permanent Global Note will be exchangeable (free of charge), in whole but not in part, for definitive Notes with, where applicable, receipts, interest coupons and talons attached upon (a) not less than 60 days' written notice being given to the Agent by Euroclear and/or Clearstream, Luxembourg (acting on the instructions of any holder of an interest in this Global Note) or (b) the occurrence of an Exchange Event. For these purposes, Exchange Event means that (i) an Event of Default (as defined in Condition 10 (Events of Default and Enforcement)) has occurred and is continuing or (ii) the Issuer has been notified that both Euroclear and Clearstream, Luxembourg, have been closed for business for a continuous period of 14 days (other than by reason of holiday, statutory or otherwise) or have announced an intention permanently to cease business or have in fact done so and no successor clearing system satisfactory to the Trustee is available. The Issuer will promptly give notice to Noteholders in accordance with Condition 14 (Notices) if an Exchange Event occurs. In the event of the occurrence of an Exchange Event, Euroclear and/or Clearstream, Luxembourg (acting on the instructions of any holder of an interest in such Permanent Global Note) or the Trustee may give notice to the Principal Paying Agent requesting exchange. Any such exchange shall occur not later than 45 days after the date of receipt of the first relevant notice by the Principal Paying Agent.

The following legend will appear on all Notes (other than Temporary Global Notes), receipts and interest coupons relating to such Notes where TEFRA D is specified in the applicable Final Terms:

“ANY UNITED STATES PERSON WHO HOLDS THIS OBLIGATION WILL BE SUBJECT TO LIMITATIONS UNDER THE UNITED STATES INCOME TAX LAWS, INCLUDING THE LIMITATIONS PROVIDED IN SECTIONS 165(j) AND 1287(a) OF THE INTERNAL REVENUE CODE.”

The sections referred to provide that United States holders, with certain exceptions, will not be entitled to deduct any loss on Notes, receipts or interest coupons and will not be entitled to capital gains treatment in respect of any gain on any sale, disposition, redemption or payment of principal in respect of Notes, receipts or interest coupons.

Notes which are represented by a Global Note will only be transferable in accordance with the rules and procedures for the time being of Euroclear or Clearstream, Luxembourg, as the case may be.

Pursuant to the Agency Agreement (as defined under “Terms and Conditions of the Notes”), the Principal Paying Agent shall arrange that, where a further Tranche of Notes is issued which is intended to form a single Series with an existing Tranche of Notes at a point after the Issue Date of the further Tranche, the Notes of such further Tranche shall be assigned a common code and ISIN which are different from the common code and ISIN assigned to Notes of any other Tranche of the same Series until such time as the Tranches are consolidated and form a single Series, which shall not be prior to the expiry of the distribution compliance period (as defined in Regulation S under the Securities Act) applicable to the Notes of such Tranche.

Any reference herein to Euroclear and/or Clearstream, Luxembourg shall, whenever the context so permits, be deemed to include a reference to any additional or alternative clearing system specified in the applicable Final Terms.

No Noteholder, Receiptholder or Couponholder shall be entitled to proceed directly against the Issuer unless the Trustee, having become bound so to proceed, (i) fails so to do within a reasonable period, or (ii) is unable for any reason so to do, and the failure or inability shall be continuing.

The Issuer may agree with any Dealer and the Trustee that Notes may be issued in a form not contemplated by the Terms and Conditions of the Notes, in which event, other than where such Notes are Exempt Notes, a new Base Prospectus will be made available which will describe the effect of the agreement reached in relation to such Notes.

APPLICABLE FINAL TERMS

Set out below is the form of Final Terms which will be completed for each Tranche of Notes which are not Exempt Notes and which have a denomination of at least €100,000 (or its equivalent in any other currency) or more issued under the Programme.

[PROHIBITION OF SALES TO EEA RETAIL INVESTORS – The Notes are not intended to be offered, sold or otherwise made available to and should not be offered, sold or otherwise made available to any retail investor in the European Economic Area (EEA). For these purposes, a retail investor means a person who is one (or more) of: (i) a retail client as defined in Article 4(1) of Directive 2014/65/EU (as amended, MiFID II); or (ii) a customer within the meaning of Directive (EU) 2016/97 (as amended, the Insurance Distribution Directive), where that customer would not qualify as a professional client as defined in Article 4(1) of MiFID II; or (iii) not a qualified investor as defined in the Prospectus Regulation. Consequently no key information document required by Regulation (EU) No 1286/2014 (as amended, the PRIIPs Regulation) for offering or selling the Notes or otherwise making them available to retail investors in the EEA has been prepared and therefore offering or selling the Notes or otherwise making them available to any retail investor in the EEA may be unlawful under the PRIIPS Regulation.]1

[PROHIBITION OF SALES TO UK RETAIL INVESTORS – The Notes are not intended to be offered, sold or otherwise made available to and should not be offered, sold or otherwise made available to any retail investor in the United Kingdom (UK). For these purposes, a retail investor means a person who is one (or more) of: (i) a retail client, as defined in point (8) of Article 2 of Regulation (EU) No 2017/565 as it forms part of domestic law by virtue of the European Union (Withdrawal) Act 2018 (EUWA); (ii) a customer within the meaning of the provisions of the FSMA and any rules or regulations made under the FSMA to implement [Directive (EU) 2016/97][the Insurance Distribution Directive], where that customer would not qualify as a professional client, as defined in point (8) of Article 2(1) of Regulation (EU) No 600/2014 as it forms part of domestic law by virtue of the EUWA; or (iii) not a qualified investor as defined in Article 2 of Regulation (EU) 2017/1129 as it forms part of domestic law by virtue of the EUWA. Consequently no key information document required by Regulation (EU) No 1286/2014 as it forms part of domestic law by virtue of the EUWA (the UK PRIIPs Regulation) for offering or selling the Notes or otherwise making them available to retail investors in the UK has been prepared and therefore offering or selling the Notes or otherwise making them available to any retail investor in the UK may be unlawful under the UK PRIIPs Regulation.]2

[MiFID II product governance / Professional investors and ECPs only target market – Solely for the purposes of [the/each] manufacturer's product approval process, the target market assessment in respect of the Notes has led to the conclusion that: (i) the target market for the Notes is eligible counterparties and professional clients only, each as defined in [Directive 2014/65/EU (as amended, MiFID II)][MiFID II]; and (ii) all channels for distribution of the Notes to eligible counterparties and professional clients are appropriate. Any person subsequently offering, selling or recommending the Notes (a distributor) should take into consideration the manufacturer['s/s'] target market assessment; however, a distributor subject to MiFID II is responsible for undertaking its own target market assessment in respect of the Notes (by either adopting or refining the manufacturer['s/s'] target market assessment) and determining appropriate distribution channels.]

1 Legend to be included on front of the Final Terms if the Notes potentially constitute “packaged” products and no key information document will be prepared in the EEA or the issuer wishes to prohibit offers to EEA retail investors for any other reason, in which case the selling restriction should be specified to be “Applicable”. 2 Legend to be included on the front of the Final Terms if the Notes potentially constitute “packaged” products and no key information document will be prepared in the UK or the issuer wishes to prohibit offers to UK retail investors for any other reason, in which case the selling restriction should be specified to be “Applicable”.

[UK MIFIR product governance / Professional investors and ECPs only target market – Solely for the purposes of [the/each] manufacturer’s product approval process, the target market assessment in respect of the Notes has led to the conclusion that: (i) the target market for the Notes is only eligible counterparties, as defined in the FCA Handbook Conduct of Business Sourcebook (COBS), and professional clients, as defined in Regulation (EU) No 600/2014 as it forms part of domestic law by virtue of the European Union (Withdrawal) Act 2018 (UK MiFIR); and (ii) all channels for distribution of the Notes to eligible counterparties and professional clients are appropriate. [Consider any negative target market]. Any person subsequently offering, selling or recommending the Notes (a distributor) should take into consideration the manufacturer[’s/s’] target market assessment; however, a distributor subject to the FCA Handbook Product Intervention and Product Governance Sourcebook (the UK MiFIR Product Governance Rules) is responsible for undertaking its own target market assessment in respect of the Notes (by either adopting or refining the manufacturer[’s/s’] target market assessment) and determining appropriate distribution channels.]

Any reference in these Terms and Conditions to “Applicable Final Terms” shall be deemed to include a reference to “applicable Pricing Supplement” where relevant.

The following are the Terms and Conditions of the Notes, which will be incorporated by reference into each Global Note (as defined below) and each definitive Note, in the latter case only if permitted by the relevant stock exchange or other relevant authority (if any) and agreed by the Issuer and the relevant Dealer at the time of issue but, if not so permitted and agreed, such definitive Note will have endorsed thereon or attached thereto such Terms and Conditions. The applicable Pricing Supplement in relation to any Tranche of Exempt Notes may specify other terms and conditions which shall, to the extent so specified or to the extent inconsistent with the following Terms and Conditions, replace or modify the following Terms and Conditions for the purpose of such Notes. The applicable Final Terms (or the relevant provisions thereof) will be endorsed upon, or attached to, each Global Note and definitive Note. Reference should be made to “Applicable Final Terms” for a description of the content of Final Terms which will specify which of such terms are to apply in relation to the relevant Notes.

This Note is one of a Series (as defined below) of Notes issued by TERNA - Rete Elettrica Nazionale S.p.A. (the Issuer) constituted by a Fourteenth Supplemental Trust Deed (such Fourteenth Supplemental Trust Deed as modified and/or supplemented and/or restated from time to time, the Trust Deed) dated 8 June 2021 and made between the Issuer and Deutsche Trustee Company Limited (the Trustee, which expression shall include any other trustee or successor as Trustee).

The Principal Paying Agent and the Paying Agents, together hereinafter referred to as the Agents.

The final terms for this Note (or the relevant provisions thereof) are set out in Part A of the Final Terms (or of the Pricing Supplement, in the case of Exempt Notes) attached to or endorsed on this Note which supplement these Terms and Conditions (the Conditions) and, in the case of a Note which is neither admitted to trading on (i) a regulated market in the European Economic Area or (ii) a UK regulated market as defined in Regulation (EU) No 600/2014 as it forms part of domestic law by virtue of the European Union (Withdrawal) Act 2018, nor offered to the public (i) in the European Economic Area or (ii) the United Kingdom in circumstances where a prospectus is required to be published under the Prospectus Regulation or the Financial Services and Markets Act 2000, as the case may be (an Exempt Note), may specify other terms and conditions which shall, to the extent so specified or to the extent inconsistent with the Conditions, replace or modify the Conditions for the purposes of this Note.

Any reference herein to Coupons or coupons shall, unless the context otherwise requires, be deemed to include a reference to Talons or talons. Exempt Notes in definitive form which are repayable in instalments have receipts (Receipts) for the payment of the instalments of principal (other than the final instalment) attached on issue. Global Notes do not have Receipts, Coupons or Talons attached on issue.

The Trustee acts for the benefit of the holders for the time being of the Notes (the Noteholders, which expression shall, in relation to any Notes represented by a Global Note, be construed as provided below), the holders of the Receipts (the Receiptholders) and the holders of the Coupons (the Couponholders, which expression shall, unless the context otherwise requires, include the holders of the Talons), in accordance with the provisions of the Trust Deed.

4.1 Redenomination

Where redenomination is specified in the applicable Final Terms or Pricing Supplement, as the case may be, as being applicable, the Issuer may, without the consent of the Noteholders, the Receiptholders and the Couponholders, but after prior consultation with the Trustee, on giving prior notice to the Principal Paying Agent, Euroclear and Clearstream, Luxembourg and at least 30 days’ prior notice to the Noteholders in accordance with Condition 14 (Notices), elect that,

with effect from the Redenomination Date specified in the notice, the Notes shall be redenominated in euro.

The election will have effect as follows:

(c) if definitive Notes are required to be issued after the Redenomination Date, they shall be issued at the expense of the Issuer: (i) in the case of Relevant Notes in the denomination of €100,000 and/or such higher amounts as the Agent may determine and notify to the Noteholders, and any remaining amounts less than €100,000 shall be redeemed by the Issuer and paid to the Noteholders in euro in accordance with Condition 6 (Payments); and (ii) in the case of Notes which are not Relevant Notes, in the denominations of €1,000, €10,000, €100,000 and (but only to the extent of any remaining amounts less than €1,000 or such smaller denominations as the Agent and the Trustee may approve) €0.01 and such other denominations as the Agent shall determine and notify to the Noteholders;

(d) if issued prior to the Redenomination Date, all unmatured Coupons denominated in the Specified Currency (whether or not attached to the Notes) will become void with effect from the date on which the Issuer gives notice (the Exchange Notice) that replacement euro-denominated Notes, Receipts and Coupons are available for exchange (provided that such securities are so available) and no payments will be made in respect of them. The payment obligations contained in any Notes and Receipts so issued will also become void on that date although those Notes and Receipts will continue to constitute valid exchange obligations of the Issuer. New euro-denominated Notes, Receipts and Coupons will be issued in exchange for Notes, Receipts and Coupons denominated in the Specified Currency in such manner as the Agent may specify and as shall be notified to the Noteholders in the Exchange Notice. No Exchange Notice may be given less than 15 days prior to any date for payment of principal or interest on the Notes;

(e) after the Redenomination Date, all payments in respect of the Notes, the Receipts and the Coupons, other than payments of interest in respect of periods commencing before the Redenomination Date, will be made solely in euro as though references in the Notes to the Specified Currency were to euro. Payments will be made in euro by credit or transfer to a euro account (or to any other account to which euro may be credited or transferred) specified by the payee or, at the option of the payee, by a euro cheque;

(f) if the Notes are Fixed Rate Notes and interest for any period ending on or after the Redenomination Date is required to be calculated for a period ending other than on an Interest Payment Date, it will be calculated:

(i) in the case of the Notes represented by a Global Note, by applying the Rate of Interest to the aggregate outstanding nominal amount of the Notes represented by such Global Note; and

(ii) in the case of definitive Notes, by applying the Rate of Interest to the Calculation Amount,

and, in each case, multiplying such sum by the applicable Day Count Fraction, and rounding the resultant figure to the nearest sub-unit of the relevant Specified Currency, half of any such sub-unit being rounded upwards or otherwise in accordance with applicable market convention. Where the Specified Denomination of a Fixed Rate Note in definitive form is a multiple of the Calculation Amount, the amount of interest payable in respect of such Fixed Rate Note shall be the product of the amount (determined in the manner provided above) for the Calculation Amount and the amount by which the Calculation Amount is multiplied to reach the Specified Denomination, without any further rounding; and

(g) if the Notes are Floating Rate Notes, the applicable Final Terms will specify any relevant changes to the provisions relating to interest.

Interest will be payable in arrear on the Interest Payment Date(s) in each year up to (and including) the Maturity Date.

If the Notes are in definitive form, except as provided in the applicable Final Terms, the amount of interest payable on each Interest Payment Date in respect of the Fixed Interest Period ending on (but excluding) such date will amount to the Fixed Coupon Amount. Payments of interest on any Interest Payment Date will, if so specified in the applicable Final Terms, amount to the Broken Amount so specified.

As used in the Conditions, Fixed Interest Period means the period from (and including) an Interest Payment Date (or the Interest Commencement Date) to (but excluding) the next (or first) Interest Payment Date.

Except in the case of Notes in definitive form where a Fixed Coupon Amount or Broken Amount is specified in the applicable Final Terms, interest shall be calculated in respect of any period by applying the Rate of Interest to:

(A) in the case of Fixed Rate Notes which are represented by a Global Note, the aggregate outstanding nominal amount of the Fixed Rate Notes represented by such Global Note; or

5.2 Interest on Floating Rate Notes and Inflation Linked Interest Notes

(A) General

Each Floating Rate Note and Inflation Linked Interest Note bears interest on its outstanding nominal amount from (and including) the Interest Commencement Date, and such interest will be payable in arrear on either:

(i) the Specified Interest Payment Date(s) in each year specified in the applicable Final Terms; or

Such interest will be payable in respect of each Interest Period.

In these Conditions, Interest Period means the period from (and including) an Interest Payment Date (or the Interest Commencement Date) to (but excluding) the next (or first) Interest Payment Date.

If a Business Day Convention is specified in the applicable Final Terms and (x) if there is no numerically corresponding day in the calendar month in which an Interest Payment Date should occur or (y) if any Interest Payment Date would otherwise fall

Where ISDA Determination is specified in the applicable Final Terms as the manner in which the Rate of Interest is to be determined, the Rate of Interest for each Interest Period will be the relevant ISDA Rate plus or minus (as indicated in the applicable Final Terms) the Margin (if any). For the purposes of this subparagraph (i), ISDA Rate for an Interest Period means a rate equal to the Floating Rate that would be determined by the Principal Paying Agent or other party specified in the Final Terms under an interest rate swap transaction if the Principal Paying Agent or that other party were acting as Calculation Agent for that swap transaction under the terms of an agreement incorporating the 2006 ISDA Definitions, as published by the International Swaps and Derivatives Association, Inc. and as amended and updated as at the Issue Date of the first Tranche of the Notes (the ISDA Definitions) and under which:

(A) the Floating Rate Option is as specified in the applicable Final Terms;

(B) the Designated Maturity is a period specified in the applicable Final Terms; and

The definition of "Fallback Observation Day" in the ISDA Definitions shall be deemed deleted in its entirety and replaced with the following: "Fallback Observation Day" means, in respect of a Reset Date and the Calculation Period (or any Compounding Period included in that Calculation Period) to which that Reset Date relates, unless otherwise agreed, the day that is five Business Days preceding the related Payment Date.

For the purposes of this subparagraph (i), Floating Rate, Calculation Agent, Floating Rate Option, Designated Maturity and Reset Date have the meanings given to those terms in the ISDA Definitions.

Investors should consult the Issuer should they need to consult the 2006 ISDA Definitions.

(B) the arithmetic mean (rounded if necessary to the fifth decimal place, with 0.000005 being rounded upwards) of the offered quotations,

(expressed as a percentage rate per annum) for the Reference Rate (being either the London interbank offered rate (LIBOR) as applicable to the currency of issue and or the Euro-zone interbank offered rate (EURIBOR), as specified in the applicable Final Terms) which appears or appear, as the case may be, on the Relevant Screen Page as at 11.00 a.m. (London time, in the case of LIBOR, or Brussels time, in the case of EURIBOR) on the Interest Determination Date in question plus or minus (as indicated in the applicable Final Terms) the Margin (if any), all as determined by the Principal Paying Agent or other party as specified in the Final Terms. If five or more of such offered quotations are available on the Relevant Screen Page, the highest (or, if there is more than one such highest quotation, one only of such quotations) and the lowest (or, if there is more than one such lowest quotation, one only of such quotations) shall be disregarded by the Principal Paying Agent or that other party for the purpose of determining the arithmetic mean (rounded as provided above) of such offered quotations.

The Agency Agreement contains provisions for determining the Rate of Interest in the event that the Relevant Screen Page is not available or if, in the case of paragraph (A) above, no such offered quotation appears or, in the case of paragraph (B) above, fewer than three such offered quotations appear, in each case as at the time specified in the preceding paragraph. In particular, if the Relevant Screen Page is not available or if, in the case of paragraph (i) above, no offered quotation appears or, in the case of paragraph (i) above, fewer than three offered quotations appear, in each case as at the Specified Time, the Financial Adviser shall request each of the Reference Banks to provide the Principal Paying Agent with its offered quotation (expressed as a percentage rate per annum) for the Reference Rate at approximately the Specified Time on the Interest Determination Date in question. If two or more of the Reference Banks provide the Principal Paying Agent with offered quotations, the Rate of Interest for the Interest Period shall be the arithmetic mean (rounded if necessary to the fifth decimal place with 0.000005 being rounded upwards) of the offered quotations plus or minus (as appropriate) the Margin (if any), all as determined by the Principal Paying Agent.

5.4 Benchmark Discontinuation

This Condition 5.3 is applicable to Notes only if the Floating Rate Note Provisions are specified in the form of Final Terms as being applicable.

(a) Independent Adviser

If the Issuer determines that a Benchmark Event occurs in relation to an Original Reference Rate when any Rate of Interest (or any component part thereof) remains to be determined by reference to such Original Reference Rate, then the Issuer shall use its reasonable endeavours to appoint and consult with an Independent Adviser, as soon as reasonably practicable, to determine a Successor Rate, failing which an Alternative Rate (in accordance with Condition 5.3(b) (Successor Rate or Alternative Rate)) and, in either case, an Adjustment Spread if any (in accordance with Condition 5.3(c) (Adjustment Spread)) and any Benchmark Amendments (in accordance with Condition 5.3(d) (Benchmark Amendments)).

102

An Independent Adviser appointed pursuant to this Condition 5.3(a) shall act in good faith and in a commercially reasonable manner and in consultation with the Issuer. In the absence of bad faith, fraud and gross negligence, the Independent Adviser shall have no liability whatsoever to the Issuer, the Paying Agents, the Trustee, the Noteholders or the Couponholders for any determination made by it pursuant to this Condition 5.3.

If (i) the Issuer is unable to appoint an Independent Adviser; or (ii) the Independent Adviser appointed by it fails to determine a Successor Rate or, failing which, an Alternative Rate in accordance with this Condition 5.3(a) and notify the Agents and the Calculation Agent of such determinations prior to the date which is ten Business Days prior to the relevant Interest Determination Date, the Rate of Interest applicable to the next succeeding Interest Period shall be equal to the Rate of Interest last determined in relation to the Notes in respect of the immediately preceding Interest Period. If there has not been a first Interest Payment Date, the Rate of Interest shall be the initial Rate of Interest. Where a different Margin or Maximum or Minimum Rate of Interest is to be applied to the relevant Interest Period from that which applied to the last preceding Interest Period, the Margin or Maximum or Minimum Rate of Interest relating to the relevant Interest Period shall be substituted in place of the Margin or Maximum or Minimum Rate of Interest relating to that last preceding Interest Period. If no Adjustment Spread is determined, a Successor Rate or Alternative Rate may nonetheless be used to determine the rate of interest. For the avoidance of doubt, this Condition 5.3(a) shall apply to the relevant next succeeding Interest Period only and any subsequent Interest Periods are subject to the subsequent operation of, and to adjustment as provided in, this Condition 5.3(a).

(b) Successor Rate or Alternative Rate

If the Independent Adviser determines that:

(i) there is a Successor Rate, then such Successor Rate shall (subject to adjustment as provided in Condition 5.3(c) (Adjustment Spread)) subsequently be used in place of the Original Reference Rate to determine the Rate of Interest (or the relevant component part thereof) for all future payments of interest on the Notes (subject to the operation of this Condition 5.3); or

(ii) there is no Successor Rate but that there is an Alternative Rate, then such Alternative Rate shall (subject to adjustment as provided in Condition 5.3(c) (Adjustment Spread) subsequently be used in place of the Original Reference Rate to determine the Rate of Interest (or the relevant component part thereof) for all future payments of interest on the Notes (subject to the operation of this Condition 5.3).

If the Independent Adviser determines (i) that an Adjustment Spread is required to be applied to the Successor Rate or the Alternative Rate (as the case may be) and (ii) the quantum of, or a formula or methodology for determining, such Adjustment Spread, then such Adjustment Spread shall be applied to the Successor Rate or the Alternative Rate (as the case may be).

(d) Benchmark Amendments

If any Successor Rate, Alternative Rate or Adjustment Spread is determined in accordance with this Condition 5.3 and the Independent Adviser determines (i) that amendments to these Conditions, the Trust Deed and the Agency Agreement, including but not limited to Relevant Screen Page, are necessary to ensure the proper operation of such Successor Rate, Alternative Rate and/or Adjustment Spread (such amendments, the Benchmark Amendments) and (ii) the terms of the Benchmark Amendments, then the Issuer shall, subject to giving notice thereof in

103

accordance with Condition 5.3(e) (Notices), without any requirement for the consent or approval of Noteholders, vary these Conditions, the Trust Deed and the Agency Agreement to give effect to such Benchmark Amendments with effect from the date specified in such notice.

In connection with any such variation in accordance with this Condition 5.3(d), the Issuer shall comply with the rules of any stock exchange on which the Notes are for the time being listed or admitted to trading.

At the request of the Issuer, but subject to receipt by the Trustee of a certificate signed by two Directors of the Issuer pursuant to Condition 5.3(e) (Notices), the Trustee shall (at the expense of the Issuer), without any requirement for the consent or approval of the Noteholders or Couponholders, be obliged to concur with the Issuer using its reasonable endeavours to effect any Benchmark Amendments (including, inter alia, by the execution of a deed supplemental to or amending the Trust Deed), provided that the Trustee shall not be obliged to agree to any Benchmark Amendments which, in the sole opinion of the Trustee, would have the effect of: (i) exposing the Trustee to any liability against which it has not been indemnified and/or secured and/or prefunded to its satisfaction; or (ii) increasing the obligations, responsibilities or duties, or decreasing the protections, of the Trustee under the Trust Deed and/or the Conditions in any way.

Notwithstanding any other provision of this Condition 5, if in the Calculation Agent’s opinion there is any uncertainty between two or more alternative courses of action in making any determination or calculation under this Condition 5, the Calculation Agent shall promptly notify the Issuer thereof and the Issuer shall direct the Calculation Agent in writing as to which alternative course of action to adopt. If the Calculation Agent is not promptly provided with such direction, or is otherwise unable to make such calculation or determination for any reason, it shall notify the Issuer thereof and the Calculation Agent shall be under no obligation to make such calculation or determination and shall not incur any liability for not doing so.

(e) Notices

Any Successor Rate, Alternative Rate, Adjustment Spread and the specific terms of any Benchmark Amendments, determined under this Condition 5.3 will be notified promptly by the Issuer to the Trustee, the Calculation Agent, the Principal Paying Agent and each Paying Agent and, in accordance with Condition 14 (Notices), the Noteholders. Such notice shall be irrevocable and shall specify the effective date of the Benchmark Amendments, if any.

No later than notifying the Trustee of the same, the Issuer shall deliver to the Trustee a certificate signed by two Directors:

(i) confirming (x) that a Benchmark Event has occurred, (y) the Successor Rate or, as the case may be, the Alternative Rate and (z) where applicable, any Adjustment Spread and/or the specific terms of any Benchmark Amendments, in each case as determined in accordance with the provisions of this Condition 5.3;

(ii) certifying that the Benchmark Amendments are necessary to ensure the proper operation of such Successor Rate, Alternative Rate and/or Adjustment Spread; and

(iii) certifying that the Issuer has duly consulted with an Independent Adviser with respect to each of the matters above.

The Trustee shall be entitled to rely on such certificate (without inquiry and without liability to any person) as sufficient evidence thereof. The Successor Rate or Alternative Rate and the Adjustment Spread (if any) and the Benchmark Amendments (if any) specified in such

104

certificate will (in the absence of manifest error in the determination of the Successor Rate or Alternative Rate and the Adjustment Spread (if any) and the Benchmark Amendments (if any) and without prejudice to the Trustee’s ability to rely on such certificate as aforesaid) be binding on the Issuer, the Trustee, the party responsible for determining the Rate of Interest (being the Principal Paying Agent, the Calculation Agent or such other party specified in the form of Final Terms, as applicable), the Paying Agents and the Noteholders and Couponholders.

(f) Survival of Original Reference Rate

Without prejudice to the obligations of the Issuer under Condition 5.3(a) (Independent Adviser) to Condition 5.3(d) (Benchmark Amendments), the Original Reference Rate and the fallback provisions provided for in Condition 5.2(B)(ii) (Screen Rate Determination for Floating Rate Notes) will continue to apply unless and until a Benchmark Event has occurred.

(g) Definitions

For the purposes of this Condition 5.3:

Adjustment Spread means either a spread (which may be positive or negative), or the formula or methodology for calculating a spread, in either case, which the Independent Adviser determines is required to be applied to the Successor Rate or the Alternative Rate (as the case may be) to reduce or eliminate, to the extent reasonably practicable in the circumstances, any economic prejudice or benefit (as the case may be) to Noteholders and Couponholders as a result of the replacement of the Original Reference Rate with the Successor Rate or the Alternative Rate (as the case may be) and is the spread, formula or methodology which:

(b) in the case of a Successor Rate for which no such recommendation has been made or in the case of an Alternative Rate, the relevant Independent Adviser or the Issuer (as applicable) determines is recognised or acknowledged as being in customary market usage in international debt capital markets transactions which reference the Original Reference Rate, where such rate has been replaced by such Successor Rate or Alternative Rate (as applicable);

(c) the Independent Adviser determines, is recognised or acknowledged as being the industry standard for over-the-counter derivative transactions which reference the Original Reference Rate, where such rate has been replaced by the Successor Rate or the Alternative Rate (as the case may be); (or if the Issuer determines that no such industry standard is recognised or acknowledged);

(d) the Independent Adviser determines (acting in good faith and in a commercially reasonable manner) to be appropriate;

Alternative Rate means an alternative benchmark or screen rate which the Independent Adviser determines in accordance with Condition 5.3(b) (Successor Rate or Alternative Rate) is customary in market usage in the international debt capital markets for the purposes of determining rates of interest (or the relevant component part thereof) in the same Specified Currency as the Notes and with an interest period of a comparable duration to the relevant Interest Period;

105

Benchmark Amendments has the meaning given to it in Condition 5.3(d) (Benchmark Amendments);

(b) due to the promulgation of or any change in the interpretation by any court, tribunal or regulatory authority with competent jurisdiction of any applicable law or regulation (including any action taken by a taxing authority),

the Calculation Agent determines in its discretion that (i) it has become illegal to hold, acquire or dispose of any relevant hedging arrangements in respect of the Inflation Index or (ii) any Hedging Party will incur a materially increased cost in performing its obligations in relation to the Notes (including, without limitation, due to any increase in tax liability, decrease in tax benefit or other adverse effect on the tax position of the Issuer, any of its Affiliates or any other Hedging Party).

Cut-Off Date means, in respect of a Determination Date, five (5) Business Days prior to any due date for payment under the Notes for which valuation on the relevant Determination Date is relevant, unless otherwise stated in the applicable Final Terms.

Delayed Index Level Event means, in respect of any Determination Date and an Inflation Index, that the relevant Inflation Index Sponsor fails to publish or announce the level of such Inflation Index (the Relevant Level) in respect of any Reference Month which is to be utilised in any calculation or determination to be made by the Issuer in respect of such Determination Date, at any time on or prior to the Cut-Off Date.

Determination Date means each of the Interest Determination Date and the Redemption Determination Date, as the case may be, specified as such in the applicable Final Terms.

End Date means each date specified as such in the applicable Final Terms.

Fallback Bond means, in respect of an Inflation Index, a bond selected by the Calculation Agent and issued by the government of the country to whose level of inflation the relevant Inflation Index relates and which pays a coupon or redemption amount which is calculated by reference to such Inflation Index, with a maturity date which falls on (a) the End Date specified in the applicable Final Terms, (b) the next longest maturity after the End Date if there is no such bond maturing on the End Date or (c) the next shortest maturity before the End Date if no bond defined in (a) or (b) is selected by the Calculation Agent. If the relevant Inflation Index relates to the level of inflation across the European Monetary Union, the Calculation Agent will select an inflation-linked bond that is a debt obligation of one of the governments (but not any

107

government agency) of France, Italy, Germany or Spain and which pays a coupon or redemption amount which is calculated by reference to the level of inflation in the European Monetary Union. In each case, the Calculation Agent will select the Fallback Bond from those inflation- linked bonds issued on or before the Issue Date and, if there is more than one inflation-linked bond maturing on the same date, the Fallback Bond shall be selected by the Calculation Agent from those bonds. If the Fallback Bond redeems, the Calculation Agent will select a new Fallback Bond on the same basis, but notwithstanding the immediately prior sentence, selected from all eligible bonds in issue at the time the original Fallback Bond redeems (including any bond for which the redeemed bond is exchanged).

Hedging Disruption means that any Hedging Party is unable, after using commercially reasonable efforts, to (a) acquire, establish, re-establish, substitute, maintain, unwind or dispose of any transaction(s) or asset(s) it deems necessary to hedge the relevant price risk of the Issuer issuing and performing its obligations with respect to the Notes or (b) freely realise, recover, remit, receive, repatriate or transfer the proceeds of any such transaction(s) or asset(s), as determined by the Calculation Agent.

Increased Cost of Hedging means that any Hedging Party would incur a materially increased (as compared with circumstances existing on the Trade Date) amount of tax, duty, expense or fee (other than brokerage commissions) to (a) acquire, establish, re-establish, substitute, maintain, unwind or dispose of any transaction(s) or asset(s) it deems necessary to hedge the market risk (including, without limitation, price risk, foreign exchange risk and interest rate risk) of the Issuer issuing and performing its obligations with respect to the Notes or (b) realise, recover or remit the proceeds of any such transaction(s) or asset(s), provided that any such materially increased amount that is incurred solely due to the deterioration of the creditworthiness of the Issuer and/or any of its Affiliates shall not be deemed an Increased Cost of Hedging.

Interest Determination Date means the date specified in the applicable Final Terms, if applicable.

Inflation Index Sponsor means, in relation to an Inflation Index, the entity that publishes or announces (directly or through an agent) the level of such Inflation Index which, as of the Issue Date, is the Inflation Index Sponsor specified in the applicable Final Terms.

Redemption Determination Date means the date specified in the applicable Final Terms, if applicable.

Reference Month means the calendar month for which the level of the Inflation Index is reported as specified in the applicable Final Terms, regardless of when this information is published or announced, except that if the period for which the Relevant Level was reported is a period other than a month, the Reference Month shall be the period for which the Relevant Level is reported.

Related Bond means, in respect of an Inflation Index, the bond specified as such in the applicable Final Terms. If the Related Bond specified in the applicable Final Terms is "Fallback Bond", then, for any Related Bond determination, the Calculation Agent shall use the Fallback Bond. If no bond is specified in the applicable Final Terms as the Related Bond and "Fallback Bond: Not Applicable" is specified in the applicable Final Terms, there will be no Related Bond.

108

If a bond is specified as the Related Bond in the applicable Final Terms and that bond redeems or matures before the End Date (i) unless "Fallback Bond: Not Applicable" is specified in the applicable Final Terms, the Calculation Agent shall use the Fallback Bond for any Related Bond determination and (ii) if "Fallback Bond: Not Applicable" is specified in the applicable Final Terms, there will be no Related Bond.

Relevant Level has the meaning set out in the definition of "Delayed Index Level Event" above.

5.4.2 Inflation Index delay and disruption provisions

(a) Delay in publication

If the Calculation Agent determines that a Delayed Index Level Event in respect of an Inflation Index has occurred with respect to any Determination Date, then the Relevant Level for such Inflation Index with respect to the relevant Reference Month subject to such Delayed Index Level Event (the Substitute Index Level) shall be determined by the Calculation Agent as follows:

(i) if "Related Bond" is specified as applicable for such Inflation Index in the relevant Final Terms, the Calculation Agent shall determine the Substitute Index Level by reference to the corresponding index level determined under the terms and conditions of the relevant Related Bond; or

(ii) if (I) "Related Bond" is not specified as applicable for such Inflation Index in the relevant Final Terms or (II) the Calculation Agent is not able to determine a Substitute Index Level under paragraph (i) above, the Calculation Agent shall determine the Substitute Index Level by reference to the following formula:

Substitute Index Level = Base Level x (Latest Level/Reference Level); or

(iii) in the case of Inflation Linked Notes which are Exempt Notes, in accordance with any formula specified in the applicable Pricing Supplement,

in each case as of such Determination Date,

where:

Base Level means, in respect of an Inflation Index, the level of such Inflation Index (excluding any "flash" estimates) published or announced by the relevant Inflation Index Sponsor in respect of the month which is 12 calendar months prior to the month for which the Substitute Index Level is being determined.

Latest Level means, in respect of an Inflation Index, the latest level of such Inflation Index (excluding any "flash" estimates) published or announced by the relevant Inflation Index Sponsor prior to the month in respect of which the Substitute Index Level is being determined.

Reference Level means, in respect of an Inflation Index, the level of such Inflation Index (excluding any "flash" estimates) published or announced by the relevant Inflation Index Sponsor in respect of the month that is 12 calendar months prior to the month in respect of the Latest Level.

The Issuer shall give notice to Noteholders, in accordance with Condition 14 (Notices) of any Substitute Index Level calculated pursuant to this Inflation provision.

109

If the Relevant Level (as defined above) is published or announced at any time on or after the relevant Cut-off Date, such Relevant Level will not be used in any calculations. The Substitute Index Level so determined pursuant to this Condition 5 will be the definitive level for that Reference Month.

(b) Cessation of publication

If the Calculation Agent determines that the level for the Inflation Index has not been published or announced for two (2) consecutive months, or the Inflation Index Sponsor announces that it will no longer continue to publish or announce the Inflation Index or the Inflation Index Sponsor otherwise cancels the Inflation Index, then the Calculation Agent shall determine a successor inflation index (the Successor Inflation Index) (in lieu of any previously applicable Inflation Index) for the purposes of the Inflation Linked Notes by using the following methodology:

(i) if at any time (other than after an early redemption or cancellation event has been designated by the Calculation Agent pursuant to this Condition 5.5), a successor inflation index has been designated by the calculation agent (or equivalent) pursuant to the terms and conditions of the Related Bond, such successor inflation index shall be designated a "Successor Inflation Index" notwithstanding that any other Successor Inflation Index may previously have been determined under paragraph (ii), (iii) or (iv) below;

(ii) if a Successor Inflation Index has not been determined pursuant to paragraph (i) above, and a notice has been given or an announcement has been made by the Inflation Index Sponsor, specifying that the Inflation Index will be superseded by a replacement Inflation Index specified by the Inflation Index Sponsor, and the Calculation Agent determines that such replacement index is calculated using the same or substantially similar formula or method of calculation as used in the calculation of the previously applicable Inflation Index, such replacement index shall be the Inflation Index for purposes of the Inflation Linked Notes from the date that such replacement Inflation Index comes into effect;

(iii) if a Successor Inflation Index has not been determined pursuant to paragraph (i) or (ii) above, the Calculation Agent shall ask five leading independent dealers to state what the replacement index for the Inflation Index should be. If four or five responses are received and, of those four or five responses, three or more leading independent dealers state the same index, this index will be deemed the "Successor Inflation Index". If three responses are received and two or more leading independent dealers state the same index, this index will be deemed the "Successor Inflation Index". If fewer than three responses are received or no Successor Inflation Index is determined pursuant to this paragraph (iii), the Calculation Agent will proceed to paragraph (iv) below; or

(iv) if no replacement index or Successor Inflation Index has been determined under paragraph (i), (ii) or (iii) above by the next occurring Cut-Off Date, the Calculation Agent, subject as provided below, will determine an appropriate alternative index from such Cut-Off Date, and such index will be deemed a "Successor Inflation Index"; or

(v) If the Calculation Agent determines that there is no appropriate alternative inflation index to Inflation Linked Interest Notes, the Issuer may redeem the Notes early at the Early Redemption Amount.

110

If the Calculation Agent determines that the Inflation Index has been or will be rebased at any time, the Inflation Index as so rebased (the Rebased Index) will be used for purposes of determining the level of the Inflation Index from the date of such rebasing; provided, however, that the Calculation Agent shall make adjustments as are made by the calculation agent (or equivalent) pursuant to the terms and conditions of the Related Bond, if "Related Bond" is specified as applicable in the applicable Final Terms, to the levels of the Rebased Index so that the Rebased Index levels reflect the same rate of inflation as the Inflation Index before it was rebased, or, if "Related Bond" is not specified as applicable in the applicable Final Terms, the Calculation Agent shall make adjustments to the levels of the Rebased Index so that the Rebased Index levels reflect the same rate of inflation as the Inflation Index before it was rebased.

(d) Material modification prior to last occurring Cut-Off

If, on or prior to the last occurring Cut-Off Date, the Inflation Index Sponsor announces that it will make a material change to the Inflation Index then the Calculation Agent shall make any such adjustments, if "Related Bond" is specified as applicable in the applicable Final Terms, consistent with adjustments made to the Related Bond, or, if "Related Bond" is not specified as applicable in the applicable Final Terms, only those adjustments to the Inflation Index necessary for the modified Inflation Index to continue as the Inflation Index.

(e) Manifest Error in publication

With the exception of any corrections published after the day which is fifteen (15) Business Days prior to the relevant Redemption Determination Date, if, within thirty (30) calendar days of publication, the Calculation Agent determines that the Inflation Index Sponsor has corrected the level of the Inflation Index to remedy a manifest error in its original publication, the Calculation Agent may, in its discretion, make such adjustments to the terms of the Inflation Linked Notes as it determines appropriate to account for the correction and will notify the Noteholders of any such adjustments in accordance with Condition 14 (Notices).

(f) Consequences of an Additional Disruption Event

If the Calculation Agent determines that an Additional Disruption Event has occurred, the Issuer may at its option:

(a) require the Calculation Agent to determine in its sole and absolute discretion the appropriate adjustment, if any, to be made to any terms of the Conditions and/or the applicable Final Terms to account for the Additional Disruption Event and determine the effective date of that adjustment; or

(b) redeem or cancel, as applicable, all but not some of the Inflation Linked Notes on the date notified by the Calculation Agent to Noteholders in accordance with Condition 14 (Notices) by payment of the relevant Early Redemption Amount, as at the date of redemption or cancellation, as applicable, taking into account the relevant Additional Disruption Event.

5.4.3 Inflation Index disclaimer

The Notes are not sponsored, endorsed, sold or promoted by the Inflation Index or the Inflation Index Sponsor and the Inflation Index Sponsor does not make any representation whatsoever, whether express or implied, either as to the results to be obtained from the use of the Inflation Index and/or the levels at which the Inflation Index stands at any particular time on any

111

particular date or otherwise. Neither the Inflation Index nor the Inflation Index Sponsor shall be liable (whether in negligence or otherwise) to any person for any error in the Inflation Index and the Inflation Index Sponsor is under no obligation to advise any person of any error therein. The Inflation Index Sponsor is not making any representation whatsoever, whether express or implied, as to the advisability of purchasing or assuming any risk in connection with the Notes. The Issuer shall not have liability to the Noteholders for any act or failure to act by the Inflation Index Sponsor in connection with the calculation, adjustment or maintenance of the Inflation Index. Except as disclosed prior to the Issue Date specified in the applicable Final Terms, neither the Issuer nor its Affiliates has any affiliation with or control over the Inflation Index or the Inflation Index Sponsor or any control over the computation, composition or dissemination of the Inflation Index. Although the Calculation Agent will obtain information concerning the Inflation Index from publicly available sources it believes reliable, it will not independently verify this information. Accordingly, no representation, warranty or undertaking (express or implied) is made and no responsibility is accepted by the Issuer, its Affiliates or the Calculation Agent as to the accuracy, completeness and timeliness of information concerning the Inflation Index.

5.6 Exempt Notes

The rate or amount of interest payable in respect of Exempt Notes which are not also Fixed Rate Notes or Floating Rate Notes shall be determined in the manner specified in the applicable Pricing Supplement, provided that where such Notes are Index Linked Interest Notes the provisions of Condition 5.2 (Interest on Floating Rate Notes and Inflation Linked Interest Notes) shall, save to the extent amended in the applicable Pricing Supplement, apply as if the references therein to Floating Rate Notes and to the Agent were references to Index Linked Interest Notes and the Calculation Agent, respectively, and provided further that the Calculation Agent will notify the Agent of the Rate of Interest for the relevant Interest Period promptly after calculating the same.

Partly Paid Notes

In the case of Partly Paid Notes (other than Partly Paid Notes which are Zero Coupon Notes), interest will accrue as aforesaid on the paid-up nominal amount of such Notes and otherwise as specified in the applicable Pricing Supplement.

Inflation Linked Interest Notes

In the case of Inflation Linked Interest Notes which are Exempt Notes interest will be paid as set out in Conditions 5.2(C) (Rate of Interest – Inflation Linked Interest Notes) and 5.5 (Inflation Linked Note provisions) or as otherwise specified in the applicable Pricing Supplement.

5.7 Accrual of interest

Each Note (or in the case of the redemption of part only of a Note, that part only of such Note) will cease to bear interest (if any) from the date for its redemption unless payment of principal is improperly withheld or refused or default is otherwise made in the payment thereof. In such event, interest will continue to accrue until whichever is the earlier of:

(A) the date on which all amounts due in respect of such Note have been paid; and

(B) as provided in the Trust Deed.

112

6. PAYMENTS

6.1 Method of payment

Subject as provided below:

(A) payments in a Specified Currency other than euro will be made by credit or transfer to an account in the relevant Specified Currency maintained by the payee with a bank in the principal financial centre of the country of such Specified Currency (which, if the Specified Currency is Australian dollars or New Zealand dollars, shall be Sydney and Auckland, respectively); and

(B) payments in euro will be made by credit or transfer to a euro account (or to any other account to which euro may be credited or transferred) specified by the payee.

Payments will be subject in all cases to (i) any fiscal or other laws and regulations applicable thereto in the place of payment, but without prejudice to the provisions of Condition 8 (Taxation) and (ii) any withholding or deduction required pursuant to an agreement described in Section 1471(b) of the U.S. Internal Revenue Code of 1986 (the Code) or otherwise imposed pursuant to Sections 1471 through 1474 of the Code, any regulations or agreements thereunder, official interpretations thereof, or (without prejudice to the provisions of Condition 8 (Taxation)) any law implementing an intergovernmental approach thereto, and (iii) any withholding or deduction required pursuant to Section 871(m) of the Code (871(m) Withholding). In addition, in determining the amount of 871(m) Withholding imposed with respect to any amounts to be paid on the Notes, the Issuer shall be entitled to withhold on any “dividend equivalent” (as defined for purposes of Section 871(m) of the Code) at the highest rate applicable to such payments regardless of any exemption from, or reduction in, such withholding otherwise available under applicable law.

Payments on the Notes that reference U.S. securities or an index that includes U.S. securities may be calculated by reference to dividends on such U.S. securities that are reinvested at a rate of 70 per cent. In such case, in calculating the relevant payment amount, the holder will be deemed to receive, and the Issuer will be deemed to withhold, 30 per cent. of any dividend equivalent payments (as defined in Section 871(m) of the Code) in respect of the relevant U.S. securities. The Issuer will not pay any additional amounts to the holder on account of the Section 871(m) amount deemed withheld.

6.2 Presentation of definitive Notes, Receipts and Coupons

Payments of principal in respect of definitive Notes will (subject as provided below) be made in the manner provided in Condition 6.1 (Method of payment) against presentation and surrender (or, in the case of part payment of any sum due, endorsement) of definitive Notes, and payments of interest in respect of definitive Notes will (subject as provided below) be made as aforesaid only against presentation and surrender (or, in the case of part payment of any sum due, endorsement) of Coupons, in each case at the specified office of any Paying Agent outside the United States (which expression, as used herein, means the United States of America (including the States and the District of Columbia and its possessions)).

Fixed Rate Notes in definitive form (other than Long Maturity Notes (as defined below) and save as provided in Condition 6.4 (Specific provisions in relation to payments in respect of certain types of Exempt Notes)) should be presented for payment together with all unmatured Coupons appertaining thereto (which expression shall for this purpose include Coupons falling to be issued on exchange of matured Talons), failing which the amount of any missing unmatured Coupon (or, in the case of payment not being made in full, the same proportion of

Each amount of principal so deducted will be paid in the manner mentioned above against surrender of the relative missing Coupon at any time before the expiry of 10 years after the Relevant Date (as defined in Condition 8 (Taxation)) in respect of such principal (whether or not such Coupon would otherwise have become void under Condition 9 (Prescription)) or, if later, five years from the date on which such Coupon would otherwise have become due, but in no event thereafter.

Payment of the final instalment will be made in the manner provided in Condition 6.1 (Method of payment) only against presentation and surrender (or, in the case of part payment of any sum due, endorsement) of the relevant Note in accordance with the preceding paragraph. Each Receipt must be presented for payment of the relevant instalment together with the definitive Note to which it appertains. Receipts presented without the definitive Note to which they appertain do not constitute valid obligations of the Issuer.

114

Upon the date on which any Dual Currency Note or Index Linked Note in definitive form becomes due and repayable, unmatured Coupons and Talons (if any) relating thereto (whether or not attached) shall become void and no payment or, as the case may be, exchange for further Coupons shall be made in respect thereof.

(B) payment of the full amount of such principal and interest at all such specified offices outside the United States is illegal or effectively precluded by exchange controls or by other similar restrictions on the full payment or receipt of principal and interest in U.S. dollars; and

(C) such payment is then permitted under United States law without involving, in the opinion of the Issuer, adverse tax consequences for the Issuer.

6.6 Payment Day

If the date for payment of any amount in respect of any Note, Receipt or Coupon is not a Payment Day, the holder thereof shall not be entitled to payment until the next following Payment Day in the relevant place and shall not be entitled to further interest or other payment in respect of such delay.

  DIR (T )  Final Redemption Amount  Specified Denomination * Max 100%; Redemption Amount M ultiplier*     DIR (0) 

The result of DIR(T) divided by DIR(0) shall be rounded (if necessary) to the fifth decimal place, with 0.000005 being rounded upwards and the Final Redemption Amount shall be rounded (if necessary) to the nearest euro cent with half a euro cent being rounded upwards.

The Early Redemption Amount payable in respect of each Note shall be the sum of (i) a principal amount determined by the Calculation Agent promptly after the time the Early Redemption Amount is capable of being determined in accordance with the formula set out above, provided that the reference to “Final Redemption Amount” shall be replaced by a reference to “Early Redemption Amount” and the DIR(T) value applicable to the Early Redemption Amount shall be utilised; and (ii) interest accrued but unpaid in respect of the period from, and including, the most recent Interest Payment Date to, but excluding, the date for redemption of the Notes where the Rate of Interest for such period shall be calculated in accordance with the applicable Final Terms.

Defined terms used in this Condition 7.13 shall have the same meanings as set out in Condition 5.2(C) provided that, DIR(T) means the value of the Inflation Index for (i) in the case of the calculation of the Final Redemption Amount, the Maturity Date and (ii) in the case of the calculation of the Early Redemption Amount, the date for redemption of the Notes, in each case calculated in accordance with the following formula where month "t" is the month and year of the Maturity Date in the case of (i) above and the month and year in which the date for redemption falls in the case of (ii) above:

122

DIR(t)=Inflation Index(t-Lookback Period 1)+[Inflation Index(t-Lookback Period 2)-Inflation Index(t-Lookback Period 1)]*[DayOfMonth-1)/DaysInMonth]

Rounded (if necessary) to the fifth decimal place, with 0.000005 being rounded upwards

If the date for redemption occurs prior to the first Interest Payment Date, a pro rata proportion of an amount equal to the product of the Initial Ratio Amount multiplied by DIR(T)/DIR(0) shall be added to the relevant Interest Amount (in respect of the period from and including the Interest Commencement Date to but excluding the date of redemption of the Notes) (such sum shall be rounded (if necessary) to the nearest euro cent with half a euro cent being rounded upwards).

The Trust Deed, the Agency Agreement, the Notes, the Receipts and the Coupons and any non- contractual obligations arising out of or in connection with them are governed by, and shall be construed in accordance with, English law. Condition 16 (Meetings of Noteholders, Modification and Waiver) and Schedule 3 of the Trust Deed are subject to compliance with the laws of the Republic of Italy.

131

USE OF PROCEEDS

An amount equal to the net proceeds from each issue of Notes will be allocated by the Issuer, as indicated in the applicable Final Terms, either:

(i) for its general corporate purposes; or

(ii) to refinancing and/or financing, in whole or in part, of existing and/or future Eligible Green Projects which meet the Eligibility Criteria (as defined below).

Use for Eligible Green Projects

Eligible Green Projects means projects with a positive impact in terms of environmental sustainability, in accordance with the Eligibility Criteria.

Eligibility Criteria means the criteria prepared by the Issuer as per its Green Bond Framework. A second party consultant appointed by the Issuer has reviewed the Green Bond Framework and has issued a Second Party Opinion.

The Green Bond Framework and the Second Party Opinion will be made available on the Issuer’s website (www.terna.it). None of these documents are incorporated into, or form part of, the Base Prospectus.

The net proceeds of the Green Bonds issued will be credited to the Treasury liquidity portfolio of the Issuer. The Issuer will track the net proceeds via its internal accounting system and will monitor the allocation to prevent any double counting in the allocation of proceeds. Pending the allocation to the Eligible Green Projects, unallocated proceeds will temporally be invested in accordance with the Issuer’s investment guidelines in treasury investment portfolio (cash and cash equivalents, tradable government bonds or other cash investments instruments, etc). An external auditor appointed by the Issuer will verify, on an annual basis, the allocation of proceeds to the Eligible Green Projects and the remaining balance of unallocated proceeds, until full allocation of the funds occurs.

The Issuer is expected to issue a report annually until full allocation occurs, and as necessary thereafter in the event of material developments on: (i) allocated amounts by Eligible Green Projects, including a brief description of the largest and most representative projects from each category; (ii) main technical data referring to the single project, when available (e.g. peak power of wind or solar plants connected); (iii) division of the allocation between refinancing and new projects; and (iv) the outstanding amount of net proceeds yet to be allocated to projects at the end of the reporting period. Where feasible, the Issuer will also report project impacts and environmental benefits linked to the single Eligible Green Project or aggregated by the categories of eligibility. The report will be made available on the Issuer's website (www.terna.it). The report will be reviewed by an external auditor.

If, in respect of an issue of Notes, there is a particular identified use of proceeds, this will be stated in the applicable Final Terms.

132

DESCRIPTION OF THE ISSUER

OVERVIEW

TERNA - Rete Elettrica Nazionale Società per Azioni (hereinafter referred to as Terna or the Issuer) is the Italian electricity transmission company responsible for planning, development and maintenance of the grid, contributing its expertise, technology and innovation (as the Transmission Operator). In addition, Terna is responsible for the transmission and dispatching of electricity (as the System Operator), with the aim of ensuring access to electricity for everyone with the highest level of quality and at the lowest possible cost.

Terna was incorporated as a joint-stock company under the laws of the Republic of Italy on 31 May 1999, and, pursuant to its By-laws, its term ends on 31 December 2100 unless such term is extended by a resolution of the Shareholders’ General Meeting. Terna operates in accordance with the Italian civil code and other laws of Italy applicable to it. Terna’s registered address is Viale Egidio Galbani 70, 00156 Rome, Italy, telephone number +39 06 8313 8111 and it is registered with the Register of Enterprises of Rome under number 05779661007. Terna’s website is www.terna.it.

As at 31 December 2020, Terna’s share capital of Euro 442,198,240 consisted of 2,009,992,000 ordinary shares with a nominal value of Euro 0.22 each unchanged at the date of this Base Prospectus. Terna’s shares are listed on the Italian Stock Exchange (Borsa Italiana S.p.A. (Borsa Italiana)).

As of 31 March 2021, on the basis of (i) the shareholders’ book, (ii) the communications received pursuant to CONSOB Regulation No. 11971 of 14 May 1999, as amended and (iii) available information, Terna’s share capital is divided as follows: CDP RETI (a joint-stock company controlled by Cassa Depositi e Prestiti S.p.A. - hereinafter referred to as CDP – which is, in turn, owned 82.77 per cent. by the Ministry of Economy and Finance of the Italian Republic) owns 29.851 per cent. of the share capital, Lazard Asset Management Llc owns 5.122 per cent. of the share capital (as discretional asset management), Norges Bank owns 1.643 per cent. of the share capital, Inarcassa owns 1.110 per cent. of the share capital, Banca d’Italia owns 1.017 per cent. of the share capital and the remaining shares are held by institutional and retail investors.

The Terna Group’s main business comprises grid operation and dispatching, infrastructure maintenance, grid development planning and carrying out of development projects of its portion of Italy’s National Transmission Grid (hereinafter referred to as the Terna Group’s Grid) as well as management of transmission and dispatching of electricity over the entire National Transmission Grid which Terna and Rete S.r.l. report in their financial statements as revenues from Regulated Activities in Italy. The Terna Group also carries out other Non-Regulated Activities including services for third parties in the Italian market (EPC, O&M, Energy Efficiency, TLC), initiatives abroad (EPC, Technical Assistance, BOOT, Concessions), Interconnectors, energy transformer production (Tamini Group (as defined below)) and manufacture of terrestrial cables (Brugg Kabel Group (as defined below)).

Terna is the main owner of the National Transmission Grid. As of 31 December 2020, the Terna Group’s Grid consisted of 74,723 kilometres of electricity lines and 889 substations.

As of 31 December 2020, the Terna Group’s total consolidated revenues amounted to Euro 2,513.5 million (as of 31 December 2019 these amounted to Euro 2,295.1 million)9 while EBITDA (Gross Operating Profit) was Euro 1,830.4 million increasing by 5,1 per cent., as compared to the same period of the previous year (Euro 1,741.2 million) (see also section “Alternative Performance Measures

9 The comparative amounts, with particular reference to revenue from construction services performed under concession in Italy (included in Regulated Activities in Italy) and from International Activities, directly including the margin earned on overseas concessions and overseas contract revenue, have been reclassified in order to improve presentation, without changing the comparative result.

(APMs)” below). Terna has been consolidating its position in the Italian transmission sector since the end of 2005 in connection with the integration of the ownership and management of the National Transmission Grid pursuant to the Decree of the President of the Council of Ministers 11 May 2004 (hereinafter referred to as the DPCM). In 2005, Terna acquired the transmission and dispatching sector of the Italian Independent System Operator (Gestore della Rete di Trasmissione Nazionale S.p.A.), an entity wholly-owned and controlled by the Ministry of Economy and Finance (hereinafter referred to as the Italian ISO). Please see also section “History and Developements” below.

HISTORY AND DEVELOPMENT

Terna’s principal activities are rooted in Italy’s history: Law No. 1643 of 1962 paves the way for nationalisation of the electricity industry, handing ENEL responsibility for all stages of the electricity supply chain, previously in private hands. The monopoly operator is able to complete electrification of the Italian Peninsula, but the driving force behind the changes that have led to the current operating environment is the process of deregulation promoted by the European Union aimed at making grid management independent. In implementation of Decree 79 of 16 March 1999, focused on separation of ownership the National Transmission Grid from management of the grid itself (involving transmission and dispatching) along the lines of the so-called “Independent System Operator” model, two new companies are established: Terna, owner of the Italian transmission grid, and GRTN (the national transmission grid operator).

In 1999, Enel established Terna as a wholly-owned subsidiary and subsequently transferred all of its electricity transmission systems and other assets that formed the Terna Group’s grid (as it then existed) to Terna. The management and the operation of the National Transmission Grid were entrusted to the Italian ISO (as defined in section “Legislative and Regulatory Framework” below) pursuant to Legislative Decree 16 March 1999 No. 79 (hereinafter referred to as the Bersani Decree).

The Bersani Decree, which required the separation of the ownership and management of the National Transmission Grid, was reversed by Law Decree 29 August 2003 No. 239 (hereinafter referred to as Decree 239/2003), as converted with amendments into law by Law 27 October 2003 No. 290 (hereinafter referred to as Law 290/2003) and the implementing measures of the DPCM (as defined in section “Legislative and Regulatory Framework” below). Law 290/2003 and the DPCM require the integration of the ownership and management of the National Transmission Grid and place certain restrictions on the ownership of the entity resulting from the integration as well as on the voting rights of the shareholders of the resulting entity. The current regulatory structure of the electricity sector is determined also by Legislative Decree 93/2011 implementing EU Directive 2009/72/EC concerning common rules on the internal market in electricity (see also “Legislative and Regulatory Framework” below).

On 23 June 2004, Enel launched an initial public offering of Terna’s ordinary shares to retail investors in Italy and a private placement with certain institutional investors in accordance with Rule 144A and Regulation S under the United States Securities Act of 1933 as amended. After the initial public offering, Enel’s stake of Terna’s share capital was reduced to 50 per cent. Pursuant to Law 290/2003 and the DPCM, which provides for the integration of the ownership and management of the National Transmission Grid and imposes certain restrictions on control of the resulting entity, Enel was required to reduce its shareholding in Terna to 20 per cent. or less by 1 July 2007 (see also “Legislative and Regulatory Framework”below). On 31 March 2005, Enel completed the sale of 13.86 per cent. of the share capital of Terna through an accelerated book-building process. In addition, on 15 September 2005, CDP acquired its 29.99 per cent. controlling stake in Terna from Enel. On 2 February 2012, Enel completed the sale of its remaining 5.1 per cent. of the share capital of Terna through an accelerated book-building procedure and, as at the date of this Base Prospectus, Enel no longer holds any stake in the share capital of Terna.

134

In 2009, Terna acquired 18,600 km of high voltage lines from Enel, thereby becoming the leading independent grid operator in Europe and the seventh largest in the world. Terna now owns 98.6 per cent. of Italy’s national grid. In the same year, Terna sold 66 per cent. of the Brazilian subsidiary, Terna Participações, to Cemig, recording a gain of over €400 million, some of which is invested in development of the Italian electricity network and some is returned cash to shareholders.

In 2011, Terna developed infrastructure of international excellence. The SA.PE.I. line (Sardinia to the mainland) starts operating, as does the Chignolo Po-Maleo line in Lombardy. Work begins on the Sorgente-Rizziconi line (linking Sicily and Calabria). Two new operating companies were established in 2012: Terna Rete Italia S.p.A. (TRI S.p.A.), responsible for Regulated Activities, and Terna Plus S.r.l. (Terna Plus), with responsibility for expanding the Non-Regulated services.

On 27 October 2014, CDP announced that its entire interest in Terna, composed of 599,999,999 shares, equal to 29.851 per cent. of the share capital, was transferred to CDP RETI. As a result of this transfer, CDP RETI currently controls 29.851 per cent. of Terna (see also section “Share capital of Terna, major shareholders and related party transactions”).

In the context of the reorganisation of the Terna Group, from 1 April 2012, Terna became the parent company of the group providing guidelines and coordinating activities of the operating companies of the Terna Group such as TRI S.p.A., being the operating company in charge of the core business activities of the Terna Group, and Terna Plus, being the operating company in charge of carrying out projects which are not core business activities of the Terna Group.

On 20 May 2014, the Terna Group signed the closing for the acquisition, originally by Terna Plus, of the entire capital of Tamini Trasformatori S.r.l. (Tamini) and of its subsidiaries. Tamini is a group of companies that produces and sells electrical transformers for industrial applications (e.g. steel and aluminium production plants) as well as for the electrical utilities (power transformers, mainly targeted to transmission and distribution networks) in Italy and in other international markets. Tamini owns four production facilities in Italy and sells its products either directly to the end customer or through Engineering and Construction (EPC) companies. Tamini is also present in the USA through a wholly owned subsidiary. On 30 October 2015, under the scope of Non-Regulated Activities, Terna finalised the business combination process between Tamini, a subsidiary of Terna Plus, and TES (which owns a company originally called TES Asia as defined below, an Indian company, considering that one share is held by Antonio Fasano on behalf of TES as a "nominee" under the Indian legislation about “one person companies”). The operation, announced to the market on 16 September 2015, has been carried out through an increase in Tamini’s share capital of around Euro 26.4 million, reserved for Holdco TES S.r.l. (Holdco TES) (controlled by the Xenon Private Equity V fund, Riccardo Reboldi and Giorgio Gussago) and the consequent transfer of all TES shares to Tamini. Following the agreement, Terna Plus held 70 per cent. of the share capital of Tamini while Holdco TES held the remaining 30 per cent. In fact, after the demerger of Terna Plus, the ownership of Tamini is held by Terna Energy Solutions S.r.l. (Terna Energy Solutions) (as better explained below).

In 2015, Terna acquired the Ferrovie dello Stato group’s high voltage grid for €757 million, consolidating its leadership in Europe with approximately 72,600 km of grid managed. In 2016, Terna focuses on strategic power lines. The Villanova-Gissi and Sorgente-Rizziconi lines enter service. The latter is a record-breaking power line, connecting Sicily and Calabria and the Italian Peninsula with the rest of Europe via the country’s high voltage electricity system. In 2018, in line with the guidance provided by the United Nations (COP21), EU guidelines and the objectives set out in the National Energy Strategy (Strategia Energetica Nazionale or SEN), Terna has stepped up the pace of investment, focusing on development of the national transmission grid in order to facilitate the integration of renewable sources and improve the system’s security. At the same time, it intends to renew the Group’s asset base in order to mitigate the risk of interruptions to supply, boost environmental sustainability, and improve the performance of maintenance activities through the use of

135

digital grid technologies, all to the benefit of the quality of the electricity service. On 19 November 2020, the “Driving Energy” Industrial Plan for the period 2021-2025 was presented by the CEO and General Manager, Stefano Antonio Donnarumma.

In order to optimise and integrate dispatching with long-term planning activities, on the one hand, and to maximise the operational efficiency of design, implementation, operations and maintenance, on the other hand, Terna has adopted an organisational structure with two key areas. Both areas report directly to the Chief Executive Officer, one being the System Operator, embodied in the “Grid Development Strategies & Dispatching” division, the other being the Transmission Operator of the National Transmission Grid.

In August 2018, the partial demerger of Terna Plus and the transfer of the demerged assets to a newly established company, named Terna Energy Solutions, came into effect. The latter’s business is focused on Non-Regulated Activities and energy solutions activities. Terna Plus will now be responsible for the Group’s development and plant construction activities in South America, and more generally for the development of new businesses around the world.

On 29 February 2020, as part of the growth strategy for Non-Regulated Activities, Terna, acting through its subsidiary, Terna Energy Solutions, completed the acquisition of a 90 per cent. interest in Brugg Kabel AG (Brugg Kabel), one of Europe’s leading manufacturers of terrestrial cables. Then, in March 2021 Brugg Kabel split into three different entities in order to better meet the needs of the business. Therefore, it remained Brugg Kabel, together with the news companies Brugg Kabel Manufacturing AG and Brugg Kabel Services AG.

A new Board of Directors was elected in May 2020, with Stefano Antonio Donnarumma appointed Chief Executive Officer and General Manager, the arrival of new managers in key roles and the election of Valentina Bosetti as Chairwoman.

On 22 May 2020, the Company established SEleNe CC S.A. (SEleNe), a joint venture 25 per cent.- owned by Terna, with the remaining shares held by three other European TSOs. The company will operate as a Regional Security Coordinator, in accordance with European Regulation 2017/1485, for the TSOs who own shares in it.

On 11 August 2020, Terna, acting through its subsidiary, Terna Plus, completed the transaction with Construtora Quebec that has led to the acquisition of a 51 per cent.interest in the Brazilian-registered company, SPE Transmissora de Energia Linha Verde I S.A. On 9 September 2020, a further interest was acquired, increasing the Group’s interest to 75 per cent.. In relation to a similar project with the aforementioned Construtora Quebec, Terna, acting through its subsidiary, Terna Plus acquired an interest in the SPE Transmissora de Energia Linha Verde II S.A, that as of May 2021 was more than 99%.

On 20 November 2020, Terna and the joint venture, SEleNe, established ESPERIA-CC S.r.l., a subsidiary as a result of its corporate governance structure, despite Terna holding a 1 per cent. interest and SEleNe a 99 per cent. interest. The company provides support services for dispatching activities (in accordance with European Regulations 2017/1485, 2015/1222 and 2019/943), but is not included among companies that carry out regulated activities which are, therefore, regulated by ARERA.

On 1 December 2020, Terna acquired a 25 per cent. interest in Equigy B.V. (Equigy), a limited liability company registered in the Netherlands and jointly controlled by Terna and the other TSOs who hold its shares. The investment represents a joint operation under IFRS 11 – Joint Arrangements. The current equity interest in Equigy held by Terna is around 20 per cent..

Regulated Activities

The Terna Group’s main Regulated Activities are the transmission and dispatching of electricity in Italy. Terna performs these activities in its role as the Italian TSO (Transmission System Operator) and ISO (Independent System Operator), under a monopoly arrangement and a government concession.

140

Electricity Transmission

Terna’s main activities in the context of the electricity transmission includes planning for development of the National Transmission Grid, the performance of construction services and the maintenance of electricity infrastructure are the three areas of responsibility included in the regulated electricity transmission business.

In respect of the planning process of the national electricity grid, the analysis of the state of the grid enables Terna to identify critical issues and development opportunities and, consequently, to plan the new works required to ensure that the system is adequate, including in the medium to long term with regard to meeting demand, operational safety, reducing congestion and improving service quality and continuity.

The new works to be carried out are included in the National Transmission Grid Development Plan (NTG Development Plan), which sets out the grid development initiatives envisaged over the next ten years, as well as the state of progress of the development works planned in previous years. The NTG Development Plan is submitted annually to the Ministry of Economic Development for approval. Law Decree no. 76 of 16 July 2020 (article 60, paragraph 3) requires Terna to prepare the National Transmission Grid Development Plan every two years instead of annually. The approval process also includes adoption by the Ministry of the Environment and Protection of Land and Sea (MATTM) in agreement with the Ministry of Cultural Heritage (MIBAC) of the opinion relating to the Strategic Environmental Assessment (SEA) pursuant to Legislative Decree 152/06.

In addition, the NTG Development Plan contains all the investments that Terna is committed to carrying out in order to guarantee the efficiency of the grid, the security of supply and of the service and the integration of production from renewable sources in keeping with the objectives identified in the recent Proposal for an Integrated National Plan for Energy and Climate (PNIEC), provided for by Regulation 2016/0375 of the European Parliament and of the Council on the Governance of the Energy Union.

All investment in development of the grid is subject to a prior cost-benefit analysis, comparing the related expenditure with the resulting benefits, expressed in monetary terms, resulting from its implementation.

Infrastructure Maintenance

Maintenance of electricity grid infrastructure is essential in order to guarantee quality of service, security of the assets managed and extension of their useful lives. These operations are carried out by Terna on the basis of a predictive and conditional approach. The tools used to support maintenance activities are subject to continuous innovation. In particular, the maintenance engineering “engine” is the expert decision support system (DSS) called MBI (Monitoring and Business Intelligence) whose engineering models are continuously updated. For scheduling and execution of operations (WFM – Work Force Management) software is used, and aerial inspection techniques for the electricity grid have now been consolidated. Terna has, for many years, participated in international benchmarking for the sector, with the aim of sharing best maintenance practices. It has consistently ranked as one of the best TSOs in terms of fault rates and the efficiency of its maintenance process.

The maintenance activities include all the actions performed on the National Transmission Grid and its components in order to preserve or to restore their effective and proper operation without making changes to their technical or functional characteristics (known as “routine maintenance”) or to renew or to extend the useful life of any component by making changes to its technical (but not functional) characteristics (known as “extraordinary maintenance”).

141

Dispatching of electricity

“Dispatching” is the set of activities necessary to ensure that there is a balance between supply and demand in the country’s electricity system. The high degree of complexity and coordination necessary to guarantee the correct operation of the system require the presence of a central coordinator, the provider of the dispatching service. This coordinator has control over a high number of both supply- side and demand-side players, and in the last few years also over production from non-programmable renewable sources. Dispatching includes planning for the unavailability of the grid and of production plants over different timeframes, forecasting national demand for electricity, comparing demand for consistency with planned production in the free energy market (the Power Exchange and over-the- counter contracts), the acquisition of resources for dispatching and monitoring power transfers for all the power lines that make up the grid.

This area of operation also includes management of the Dispatching Services Market (DSM), through which the resources for dispatching services are procured. In particular, “real-time” control of the National Electricity System is ensured by the National Control Centre, the nerve centre for Italy’s National Electricity System, which coordinates the other centres around the country, monitors the system and dispatches electricity. The Centre intervenes, by issuing instructions to producers and Remote Centres, in order to modify supply and capacity on the grid. To avoid the risk of prolonged power outages, it may also intervene in an emergency to reduce demand.

Operation and development of the National Transmission Grid

Operation

The operation of the National Transmission Grid is carried out by TRI S.p.A. through the National Control Centre and the local dispatching centres.

(a) Plant management and control

TRI S.p.A determines the configurations and the sequences for the switches, known as “breaker switches”, that connect the various components of the National Transmission Grid. TRI S.p.A is required to take all necessary actions to implement and maintain the configurations and sequences as applicable to the Terna Group’s Grid. TRI S.p.A. also determines the configurations and sequences for the switches for other National Transmission Grid owners.

Furthermore, TRI S.p.A. defines the unavailability plans for the Terna Group’s Grid and coordinates the unavailability plans of the producers and other users of the National Transmission Grid with its own plans and with the ones of the other owners of the National Transmission Grid in accordance with criteria of security, reliability and efficiency as well as the maintenance of security, continuity of supply of electrical energy and cost control.

(b) Response operations

TRI S.p.A. is required to promptly respond to all hazardous conditions that arise from any failure or malfunction of any part of the Terna Group’s Grid and, if possible, rectify such failure or malfunction.

If a part of the Terna Group’s Grid is required to be temporarily taken out of service for maintenance or other projects, TRI S.p.A.’s specialist personnel (i) implements certain procedures to create safe conditions for maintenance or other projects to be conducted and (ii) implements procedures for resumption of service.

TRI S.p.A. has currently three local integrated centres, named CCT, in Turin, Scorzè (Venice) and Naples for dispatching and operation activities.

Development

Terna and TRI S.p.A. also engage in development activities related to the expansion and the upgrade of the National Transmission Grid. Development activities for the National Transmission Grid include:

 identification of network developments aimed at the resolution of the current criticalities of the National Transmission Grid as well as possible problems envisaged in future scenarios of load demand, generation and interconnection with other countries;

 identification of network developments that offer benefits for the electrical system allowing greater use of more competitive generation plants limited in production for network bottlenecks;

144

 identification of network developments that allow renewable source integration in to the decarbonisation scenario in accordance with National and European energy policy target;

 costs/benefits analysis in order to quantify the benefits of network developments on the National Transmission Grid and to prioritize those that lead to greater benefits;

 increasing the transmission capacity of the interconnections with foreign countries;

 increasing operating flexibility and resilience of grid;

 preventive environmental assessments so as to ensure that network developments are consistent with the maximum respect for the environment.

The development activities for the National Transmission Grid concern mainly the planning, the design and the construction of projects. They are included in the National Transmission Development Plan, prepared every two years (Law Decree no. 76 of 16 July 2020 article 60, paragraph 3) in compliance with the Concession governed by the relevant Convention issued by Ministerial Decree on 15 December 2010 (hereinafter referred to as the Concession; see also “Legislative and Regulatory Framework” below) and the Legislative Decree 93/2011.

Terna is particularly conscientious about National and European energy policy objectives, in particular about the integration of renewable energy sources, the integration of the electricity market and the security of supply guaranteeing sustainable grid development; these goals represent the four main drivers of the TDP: decarbonisation, market efficiency, safety of supply and sustainability.

Terna is also part of ENTSO-E, the European Network of Transmission System Operators composed of 42 European Transmission System Operators from 35 countries. ENTSO-E has been given legal mandates by the EU’s Third Legislative Package for the Internal Energy Market in 2009 and updated with Clean Energy Package provisions in 2019 aimed at further liberalizing the gas and electricity markets in the EU. The main objectives of ENTSO-E are to set up the internal energy market and to ensure its optimal functioning, to promote reliable operation as well as optimal management and development of the European electricity transmission network. Part of these objectives are achieved by ENTSO-E through the non-binding European Ten-Years Network Development Plan (hereinafter referred to as TYNDP), which is the most comprehensive and up-to-date European-wide reference for the transmission network. TYNDP points to significant investments in the European power grid in order to help achieve the European energy policy goals. The TYNDP includes European investments in transmission infrastructures and monitors developments in the capacity of transmission networks to promptly identify possible gaps, particularly with regard to cross border capacities. ENTSO-E’s activities focus on four courses of action (security of supply, functioning of the energy market, promotion of energy saving, and promotion of the interconnection of energy networks), which generate new tasks for ENTSO-E (implementation of the Regional Coordination Centres - RCC, enhanced cooperation with distribution system operators, digitisation of networks and development of demand response). These activities will be developed in line with the new climate policies previously set out by the European Commission with the launch of the so-called European Green Deal, a roadmap that seeks to make the EU the first climate-neutral continent by 2050. Major investments planned by Terna in the short-medium term and long term are included in the TYNDP. Furthermore, the above-mentioned development plan recognizes the central and strategic position of Italy in the Mediterranean basin in particular with reference to the integration of European electric systems of the Balkans and the North African shore. Last ENTSO-E TYNDP, TYNDP 2020, was published on 15 February 2021.

145

Terna is also a member of Med-TSO: the association that brings together the TSOs from 19 Mediterranean countries, with the aim of promoting the standardisation of development plans and the coordinated management of grids. Terna hosts the association’s registered office and operational headquarters in Rome and appoints its Secretary General.

Terna is a member of GO15, the association gathering the 17 largest system operators of the world, holding its Vice Presidency for 2021 and Presidency for 2022. The association’s aim is to cooperate and share best practices in the electricity transmission field this is done by putting together the different experiences of system operators managing complex energy systems and covering the entire globe.

Engineering, construction, operation and maintenance

The gradual liberalisation of laws and regulations regarding the production and sale of electricity in Italy has led to greater demand from independent power producers for services relating to the engineering, construction, operation and maintenance of high voltage and very high voltage networks and systems for connection to the National Transmission Grid.

With reference to activities designed to increase the connection capacity of the National Transmission Grid with the electricity systems of neighbouring countries, the so-called “merchant lines”, the Decree of the Ministry of Productive Activities of October 2005 clarifies that concession owners may not participate in merchant lines, in compliance with EU Regulation 1228/2003. Terna will evaluate the possibility of contributing to certain merchant line initiatives as a general contractor.

A further step towards defining opportunities within the sphere of non-traditional activities in Italy was the signing of the Memorandum of Understanding (hereinafter referred to as the MoU) on 16 December 2013 with several trade federations, in the presence of the Minister for Economic Development and of Confindustria. The MoU regards the construction and management of interconnection infrastructure with foreign countries (Interconnections or Interconnector) pursuant to article 32 of Italian Law 99/2009 and aimed at providing a basis for negotiation for future agreements with the parties winning the tender procedures held by Terna in 2009 and 2010. For more details about the development of the Private Interconnectors see the section below.

As part of the ongoing activities linked to development of the electricity interconnector project between Italy and Tunisia (the Elmed project), on 22 October 2019, Terna and STEG, Tunisia’s state-owned electrical utility, signed a memorandum of cooperation and a partnership agreement with a view to developing reciprocal exchanges and collaborating on areas of interest in relation to electricity infrastructure, such as for example live-line working, HV lines and stations and operation of the electricity system.

Via Elmed, work continued on development of the electricity interconnector project between Italy and Tunisia. In execution of two financing agreements granted by the World Bank to the Republic of Tunisia regarding the project to provide technical assistance for the Tunisia - Italy electricity interconnector, in January 2019 Elmed signed two subsidiary agreements with the Republic of Tunisia, appointing it as the implementing agency for the project components relating to preparatory studies and project management. On 30 April 2019, the Italian Minister for Economic Development and the Tunisian Minister for Industry signed an “Intergovernmental agreement regarding the development of electricity transmission infrastructure to maximise electricity exchanges between Europe and North Africa”, in which the activities entrusted to Elmed are also covered. On 27 May 2020, Terna and STEG applied to the EU’s Connecting Europe Facility (CEF) for funding for the Tunisia - Italy electricity interconnector. The CEF was set up to enable the delivery of projects of common interest.

The Terna Group’s operations and maintenance services are, for the most part, provided to industrial companies or other power companies that own high voltage and very high voltage transmission networks and systems. As of 31 December 2020, not regulated and international revenue amounted

146

totally to Euro 364.6 million, showing an increase of Euro 124.5 million compared to 31 December 2019. The increase in Non-Regulated revenue, totalling Euro 129.3 million, primarily reflects revenue the overall contribution resulting from the integration of Brugg Kabel, partly offset by a decline in revenue at Tamini and from services for third parties linked to the COVID-19 health emergency, as well as reduced revenue from private interconnector projects pursuant to Law 99/2009, compared with the previous year. International revenue is down Euro 4.8 million, essentially reflecting the higher penalties applied to suppliers in the previous year in connection with contract work in Brazil and Uruguay.

Non-Regulated Activities

The Terna Group offers products and services pursuing new business opportunities thanks to the experience, technical skills and innovation capabilities acquired through the management of complex systems.

The main areas in which these activities are developed are:

 Connectivity (as an Asset Based Business)

Terna Connectivity business is evolving into a fully integrated model mainly based on dark fiber trade. The key drivers of Terna Connectivity strategy can be summarized as follows:

○ Selling “dark fiber” right of use to TLC operators;

○ Increasing the business coming from the pylons that the Group has in Italy, both for the digitalization of the country (e.g. hosting antennas for 5G and wireless connectivity) and for the advanced monitoring through IoT technology (weather monitoring, fire prevention);

○ Evaluating additional TLC opportunities strictly related to assets (basic services related to connectivity and distributed lean data center).

 Energy Solutions (as a Competence Based Business)

Energy Solutions provides customers with a wide range of technical solutions aimed at enabling them to catch the opportunities arising from the new energy market based on renewable distributed generation and the evolution from consumer/producer to pro-sumer. Energy Solutions include :

○ Grid infrastructure, i.e. solutions to manage connection to electric grid;

○ Energy efficiency, i.e. solutions in order to create value for customers in terms of energy and environmental benefits, of identification of potential efficiency improvements, of management of energy efficiency certificates and to improve sustainability performance (leveraging ATEI competences);

○ Smart solutions, including integration of distributed generation, storage and microgrids;

○ Services, including energy performance contracts and maintenance of energy infrastructure (PV plants, substations);

○ Potential additional opportunities from industrial processes digitalization (for example predictive maintenance).

147

 Private Interconnectors pursuant to Law 99/2009

Terna is developing projects relative to interconnectors with other countries. The cross-border interconnectors with Montenegro (completed in December 2019), France (in an advanced realization stage), Austria (preliminary works started), Switzerland and Slovenia (under design and permitting) are part of this overall project.

On 28 December 2019, the first pole of the 500kV direct current interconnection line between the substations of Villanova (Italy) and Lastva (Montenegro), part in submarine cable and part in terrestrial cable, covering a total distance of approximately 445 km entered into commercial operation. It allowed the realization of a new transmission capacity between Italy and Montenegro of 600 MW, of which 200 MW was available under a third-party access exemption to the private investors selected in accordance with L. 99/2009.

The private part of the project is owned by Monita Interconnector S.r.l. (Monita), a company that Terna sold on 17 December 2019 to the Consortium Interconnector Energy Italia S.C.p.A. (Consortium that groups together the private investors having access to the 200 MW exempted cross-border capacity between Italy and Montenegro). Starting from the date of entry into commercial operation of the link, until the end of the 10 years exemption period, Terna manages operation and maintenance activities (ordinary and extraordinary) of the interconnector on payment of an annual fee by Monita.

In accordance with the provision of Italian Law 99/2009, Terna Group has continued working on the construction of the HVDC private line, exempted for 350 MW to the Piemonte Savoia S.r.l. (company held by private investors selected according to the same law), corresponding to the Italian portion of one of the two direct current lines forming the interconnector between Piossasco (Italy) and Grande Ile (France). With reference to the status of cable works, the entire power cable laying (approximately 95 km) was completed in December 2020. Remaining activities include optic fiber cable laying and the installation of monitoring systems, whose completion is foreseen by mid-June 2021. Regarding the Piossasco converter station, the civil works and assembly of all the electromechanical equipment were completed in December 2020. Given the delays on construction activities on both the Italian and French sides, due to the COVID-19 pandemic emergency, the interconnector’s entry into service is currently expected to take place in the fourth quarter of 2021.

The Italy-Austria interconnector (the Reschenpass project) concerns the realization of a new 220kV AC interconnection line between the existing Glorenza (Italy) and the future Nauders (Austria) substations through an underground cable of around 28 km (26 km on the Italian side) and the necessary adaptations of the internal grid. The project will increase cross-border interconnection capacity between Italy and Austria by around 300 MW, which will almost double the currently available capacity. The investment of the project is expected to be approximately €85 million.

On 16 March 2020, the exemption process was formally started with the exemption request sent to the Ministry for Economic Development (MiSE) by Resia. The exemption request was subsequently forwarded by MiSE to the ARERA for the expression of the relevant opinion. On 6 May 2020, Resia submitted the exemption request, translated into English and German, to the Austrian Regulator, E-Control. On 17 November 2020, ARERA granted its approval for the issue of the exemption decree to Resia.

It is recalled that, in accordance with the Law n. 99/2009, on 16 July 2018 Terna set up the special purpose vehicle, Resia Interconnector S.r.l., (Resia) in order to prepare and submit, on mandate of the private investors, a third-party access exemption request for a transmission

148

capacity of 150 MW and a period of ten years, with reference to the Italian part of the Reschenpass project. On 18 April 2019, Terna obtained the authorization for the realization and operation of the the 220kV underground cable between the Italian/Austrian border (at the Resia Pass) and the Glorenza substation, which, together with the extension of the existing Glorenza substation and the related works, constitutes the Italy-Austria interconnector envisaged pursuant to Law 99/2009. On the Austrian side, APG (the Austrian TSO) obtained all the authorizations in the second half of 2019.

Moreover, on 1 October 2019, the MiSE transferred to Resia the authorisations relative to the interconnector.

The Italy – Switzerland Interconnector project involves the development of new transmission lines between Italy and Switzerland, with the aim to increase by about 1 GW the interconnection capacity between the two countries.

Regarding the Interconnector Italy – Slovenia project, Terna planned the realization of a direct current line, partly in the form of an undersea cable, between the substations of Salgareda (IT) and Divaça/Beriçevo (SL), together with some internal reinforcements on Italian and Slovenian grids. The expected increase in cross-border capacity of approximately 1 GW will make it possible to more than double the current interconnection capacity.

 Transformers through Tamini Group

Tamini Group operates in the electromechanical sector and is a leader in the design, production, commercialisation and repair of power transformers for electricity transmission and distribution grids, of industrial transformers for the steel and metals industry and of special transformers for convertors used in electrochemical production.

With a hundred years of experience, Tamini has a well-established name in Italy and overseas, thanks to its technological and engineering capabilities, combined with the degree of customisation and production flexibility it can offer.

Tamini has six production plants in northern Italy and two trading companies in the United States and India. The Rodengo plant specialises in services, whilst the Novara production plant continues to manufacture coils, operating as a service centre for all the production sites that manufacture for both the Power and Industrial sectors.

 Acquisition of Brugg Kabel

On 29 February 2020, in implementation of the preliminary agreement signed on 20 December 2019, Terna acquired a 90 per cent. interest in Brugg Kabel, one of the leading European operators in the terrestrial cable sector, specialising in the design, development, construction, installation and maintenance of electrical cables of all voltages and accessories for high-voltage cables. The acquisition, which Terna financed with its own funds, was finalised through the subsidiary Terna Energy Solutions. The preliminary amount paid for acquisition of the equity interest is CHF25.8 million.

The acquisition of Brugg Kabel provides Terna with a centre of excellence for research, development and testing in one of the core technologies for the TSO, such as terrestrial cable technology.

In particular, the transaction gives Terna the opportunity to rapidly integrate core competencies, by acquiring a company featuring:

149

 specialisation in 150kV cables with standards in line with those Terna requires;

 HV cable production capacity in line with Terna’s requirements;

 expertise consolidated over 120 years, which as been widely verified by Terna;

 significant potential synergies with the Group’s Non-Regulated Activities.

It should be noted that Terna’s Development Plan, in line with the objectives of greater sustainability and resilience for the NTG, envisages doubling the number of terrestrial cables over the next 10 years. Consequently, the development of distinctive expertise in the underground cable sector to support cable design and construction activities, as well as O&M, may well have a key role to play in Terna’s future.

From an organisational point of view, Samuel Ansorge has been confirmed in the role of COO, while Agostino Scornajenchi has been appointed Executive Chairman.

International Activities – Operator on the international market

The Terna Group offers products and services abroad with a view to diversifying its activities carried out in Italy and collaborates with energy operators with a consolidated international presence. The development activities focus on geographical areas requiring investments in transmission infrastructures that also have stable political and regulatory frameworks and a risk/return profile in line with that of Terna.

As to the International Activities, Terna is committed to focusing its position within the European continent by strengthening Italy’s role as the electricity hub between Europe and the Mediterranean.

Terna’s strategic priorities with regard to its overseas operations include:

 Europe: to strengthen its presence with the aim of enabling Italy to become an energy hub servicing the Mediterranean area;

 Latin America: to consolidate its position in countries of interest by acquiring further concessions, developing projects already in progress in Brazil and Peru and operating the lines that have entered service in Brazil and Uruguay; and to integrate the Issuer’s value proposition with services for third parties falling within the scope of both regulated and non-regulated activities;

 Other geographical areas: to develop services supporting the ecological transition, and that involve a low level of risk and absorb a limited amount of capital.

Moreover, activities in South America are focused on completing the construction of 132 km of new 138kV lines in Peru between Aguaytìa and Pucallpa.

In Uruguay, Terna has completed the construction of the 213 km Melo-Tacuarembò 500kV transmission line; and the line has been in operation since 24 October 2019.

In Brazil, Terna has completed the construction of the lines and substations for the two concessions, Santa Maria in the State of Rio Grande do Sul and Santa Lucia in the State of Mato Grosso.

In addition, onsite activity began and engineering work and the acquisition of rights and easements for the SPE Transmissora de energia Linha Verde II project began. This is the first of the two concessions

150

covered by the preliminary agreement with Construtora Quebec, regarding the construction of a 150- km 500kV power line in the State of Minas Gerais.

Acquisition of the second concession covered by the above agreement was completed in August 2020. This regards the SPE Transmissora de Energia Linha Verde I project, involving the construction of a 150-km 500kV power line dubbed the “Governador Valadares-Mutum” in the State of Minas Gerais. The consents process and related design engineering work is underway.

In Peru, work, which began in 2017, on the construction of 132 km of new 138kV lines between Aguaytìa and Pucallpa is continuing. Construction, which was temporarily interrupted in March by the lockdown imposed by the government in response to the COVID-19 pandemic, resumed in July 2020. In the meantime, the procurement of transmission line materials and the related civil engineering works have been completed and the project is expected to reach completion in the first half of 2021.

Overseas initiatives of interest to Terna are the acquisition and operation of transmission systems abroad by taking part in international concession, the provision of consulting and technical assistance services, energy solutions such as high value-added non-traditional activities and Project management.

RESEARCH AND DEVELOPMENT

The role of the electric energy vector is crucial to enable the energy transition; all renewable generation technologies are based on the conversion of mechanical or thermal energy (wind, sun, geothermal, waves, etc) into electricity and energy efficiency technologies are almost exclusively based on electric vector (heat pumps, e-mobility, induction cooking etc.).

To do so, priorities are: making Europe (and World) more energy efficient by accelerating investments and interconnections, building more and more integrated energy markets by constructing the necessary transmission lines, protecting consumer rights and achieving high safety standards in the energy sector.

In this context, Innovation & Digitalization will also be crucial during this path and the reinforcement of R&D activities is a priority for Terna Group; in order to accomplish his mission as a TSO, Terna has to guarantee the fulfilment of key system needs (RES integration, adequacy, reliability) at the lowest possible cost for the system with high quality standards.

A single solution does not exist: a full set of coordinated measures is needed to accomplish this challenging task. From Terna’s point of view, the most relevant “enablers” appear to be: . Infrastructure development: Reinforcement of the national grid (eg. Tyrrhenian Link) and interconnections with foreign countries, investments to compensate for loss of inertia and voltage control (compensators, reactors, statcom) and to increase resilience; . Renewables Development: Increase installation rates from currently <1GW per year to at least 4 GW per year to reach Clean Energy Package targets (6 GW/year in light of the Green Deal). Furthermore, it is necessary to plan sufficiently in advance the quotas for auctions consistent with the 2030 objectives; . Simplification and Acceptability: Simplification and acceleration of the permitting processes and more effective awareness campaigns to improve the social acceptability of renewables; . Capacity Market: The power generation fleet will have to evolve by progressively replacing thermal capacity with variable renewable sources and storage systems. This transition will have to be guided by capacity market auctions as well as by auctions for renewables and dedicated auctions for pumped-hydro and electrochemical storage; . Storage: Implementation of new pumped-hydro and electrochemical storage systems to provide active and reactive power control to the system (voltage, frequency, inertia and short circuit power), ensure adequacy, manage overgeneration and residual load ramps;

151

. Flexibility resources: Evolution and integration of markets to meet new needs and to facilitate the participation of new flexibility resources in the grid ancillary services markets (DSR and storage systems, already promoted with the ongoing UVAM & UPI pilots, fast reserve, pilot to test provision of secondary reserve by UVAM and storage).

Digitalization contributes to further market facilitation and enables new actors and new roles, centering around prosumers and active system management.

A cyber physical grid is in the making. It is composed of the physical part on the one hand – towers, cables, wires, substations etc. – and the increasing digital grid on the other.

The latter will allow for the integration of models, tools, platforms and information.

The Digital Grid will enable not only the automated and coordinated decision-making inside the power system and all the other parties that constitute the electricity value chain. In such context, as a point of reference, Terna has launched several innovative projects:

■ Dedicated solutions for Transmission operator activities, which include:

○ Full digitization of transmission network, which already counts over 200 digital stations, enabling the application of Big Data and Advanced Analytics tools;

○ Robotization of grid inspection and monitoring. Currently are in pilot phase new technologies such as drones and magnetic-inductive robots;

○ New solutions to improve monitoring of underground cables health, both for AC and DC High Voltage cable systems (including joints and terminations, the most "delicate" components of a cable system);

■ Terna is investing heavily also for the System Operator activities, which include:

○ Enhance accuracy of forecasting for Renewable generation through state-of-art probabilistic models;

○ Continuously improve real-time operations through advance analytics applications. The extensive penetration of distributed resources requires indeed a increasingly quicker intervention capability for the TSO;

○ Innovative solution for the observability on the real-time behavior of Distributed Energy Resources;

○ Several pilot projects on new flexibility resources, as a brand-new testing field for utility scale storage system, currently operating in Sardinia and Sicily. Terna has also already designed and regulated the participation of aggregators to ancillary service market, including also aggregators of electrical vehicles (in other words the Vehicle 2 Grid).

INNOVATION

Innovation and digital transformation are essential in the current increasingly complex energy context. Terna focuses its model of development on technology trends which are relevant to its business.

152

The current ecological transition process requires a new systemic and organic approach to innovation, based around the acceleration of a portfolio of effective research, development and innovation initiatives in keeping with the Groups strategies. Terna has decided to further speed up its innovation process, in order to promote research and development into ideas and synergistically manage the innovation ecosystem. Within the framework of an innovation ecosystem, Terna promotes initiatives with universities and research centres, works with peers and major industrial players, and engages start- ups and small and medium-sized enterprises.

Innovation is one of the pillars of Terna’s businesses. Indeed, in the new 2021-2025 Industrial Plan more than €900 million has been earmarked for innovation and digitalisation. During the second half of 2020, the new Terna management drew up the 2021-2025 Innovation Plan, which sets out the new innovation model.

Terna has developed an innovation model geared towards meeting new needs and generating value for the company and its stakeholders, adopting a concrete, open, inclusive and distributed approach:

 Concrete: from the needs of business to the concrete solutions that can resolve them, through the generation and development of new ideas and the implementation of innovative projects, with a structured process of protection and enhancement of Intellectual Property.

 Open: with the involvement of external actors such as start-ups, universities and other entities that play the dual role of enablers and recipients of the benefits of innovation.

 Inclusive: innovation initiatives involve the company's people, and this helps spread the culture of innovation.

 Distributed: all the different organisational structures participate in the development of innovation ideas and projects, aided also by the Innovation Factories, which serve as a link between central innovation and the different company structures.

Terna has outlined the evolution of the technology scenario and identified the emerging issues for the future of the Italian energy system. And based on their potential impact on business, Terna has chosen some clusters on which to focus innovation activities:

o Digital

o Advanced Materials

o Energy Tech

o Robotics

The new Innovation Plan is focused on critical enabling technologies, including a balanced portfolio of initiatives to grasp even the most disruptive challenges.

The COVID-19 emergency posed Terna another important challenge regarding digital systems to support operations strongly impacted by remote working during lockdowns. Several initiatives have been implemented and launched that have enabled full remote operations, with a gradual shift of working practices towards a new normal. Specific actions have also been undertaken in support of internal processes and skills to promote and sustain NexTerna, a key element of the company’s resilience during the COVID-19 health emergency.

153

STRATEGY AND BUSINESS PLAN

2021-2025 “Driving Energy” Industrial Plan

The 2021-2025 Industrial Plan, Driving Energy (the Industrial Plan 2021-2025 or the Plan), aims to confirm and reinforce Terna’s central role in managing and enabling the Italian energy system and the ecological transition, and as the main driving force behind the country’s efforts to achieve the targets in the European Green Deal and Italy’s Integrated National Plan for Energy and the Climate, above all the 55 per cent. reduction in emissions by 2030, marking the first step on the road to achieving zero emissions by 2050.

The exponential increase in global primary energy consumption, the increase in CO2 emissions and the impact on our planet’s ecosystem are evidence of the fact that the energy model on which the planet’s development has depended in recent years is no longer sustainable. It is, therefore, necessary for national and international institutions to commit to a progressive and as rapid as possible decarbonisation and improved efficiency across all forms of energy. In this context, the electricity sector has a central role to play in achieving the energy system’s overall decarbonization goals, thanks to the intrinsic efficiency of electricity as an energy carrier compared with other forms of energy and the technological maturity of renewable energy sources (RES).

This transformation will not have zero impact on the electricity system but will face the Issuer with a series of challenges that must be met in order to ensure decisive and effective delivery of the ecological transition, whilst maintaining the current high levels of service quality and, at the same time, avoiding an excessive increase in the cost to society.

The growing presence of renewable energy plants has a significant impact on the way in which Terna manages the grid. These intermittent sources of energy, not as flexible as traditional power plants and sometimes far away from centres of consumption, result in an increase in grid congestion, especially on sections connecting the south with the north.

In addition, the growing frequency of extreme climate events, allied with the structural nature of the Italian transmission grid, puts major demands on the TSO, which is called on to protect and manage the national grid in order to guarantee the security of electricity supply.

Under Terna’s approach, to ensure that the ecological transition provides the necessary security, the system requires the following key elements: investment in the grid (to enable security, resilience and the integration of non-programmable RES), the installation of renewable energy sources and storage systems, providing additional storage capacity for electricity that will allow the system to operate and minimize overgeneration.

With specific regard to investment in the grid, Terna’s Plan focuses on efforts to significantly accelerate sustainable investment, the integration of non-programmable renewable sources and the strengthening of system security and resilience, thereby supporting the ecological transition and the phase-out of coal. The aim of this strategy is to resolve grid congestion and upgrade the transmission backbones that play an essential role in linking places of production with consumption. This goal will be achieved by reinforcing connections between the north and south of the country and with the islands, and by boosting cross-border interconnection capacity. To achieve this, the Terna Group plans to invest a total of €9.2 billion over the next five years.

Consequently, the strategic guidelines for the various areas (i.e. Regulated Activities, Non-Regulated Activities, International Activities) of the Terna Group have been identified.

154

Regulated Activities

In terms of Regulated Activities, which continue to represent the Group’s core business, Terna plans to invest €8.9 billion, a record level of investment for Italy and up 22 per cent. compared with the target of €7.3 billion set in the previous Plan. This investment will bring major benefits for the entire system, well beyond their initial cost, and will focus on developing, modernising and strengthening the national transmission grid, confirming Terna’s role as the enabler of an increasingly complex, sustainable and technologically advanced electricity system. In addition, 95 per cent. of this investment is classifiable as green under the criteria used in the EU Taxonomy currently being revised.

The most important projects include the Tyrrhenian Link, which will contribute to the decarbonisation of Sardinia, integrating different market areas with major benefits in terms of efficiency; the power line that will link the Colunga zone (Bologna) with the Calenzano zone (Florence), significantly boosting exchange capacity between south-central and north-central Italy; the power line that will connect southern and northern Sicily between Chiaramonte Gulfi (Ragusa) and Ciminna (Palermo), improving the quality and continuity of electricity supply in the region; and SA.CO.I.3, the new tri-terminal high- voltage direct current(HVDC)connection between Sardinia, Corsica and the Italian mainland.

As a result of this investment, the value of the Issuer’s regulated asset base (RAB) will rise to €21.8 billion in 2025, with a CAGR of 6 per cent. over the life of the Plan, a significant increase compared with the previous Plan.

Non-Regulated Activities

Non-Regulated Activities will focus on the development of innovative, digital solutions to support the ecological transition, fully in line with the Group’s core business. These activities include:

– Energy Solutions: services for high-voltage infrastructure and smart grids, and energy efficiency services offered through Avvenia;

– Connectivity: the offer of connectivity, dark fibre and housing and hosting services for telecommunications providers;

– Manufacturing: the production of power transformers and terrestrial cables carried out by Tamini and Brugg, whose growth will help to drive efficient delivery of Terna’s existing strategy for insourcing distinctive capabilities.

– Interconnectors: services for the construction of electricity interconnection by private investors different from TSOs

Non-regulated Activities are expected to contribute a cumulative total of approximately €450 million to the Group’s EBITDA over the life of the Plan, in return for limited investment and risk exposure.

International Activities

In terms of International Activities, Terna now operates in a number of Latin American countries, where we aim to maintain a presence in order to exploit its expertise and build on its know-how in cross-border high-voltage and very high-voltage connections. In addition to the projects currently underway in Brazil, Peru and Uruguay, the 2021-2025 Industrial Plan envisages that we will take advantage of new opportunities capable of driving further EBITDA growth in return for low levels of risk and modest capital outlays. Terna expects to invest up to €300 million in new projects over the life of the Plan.

Terna thus expects that its International Activities will contribute a cumulative total of over €200 million to the Group’s EBITDA over the life of the Plan.

155

To help drive delivery of the Plan and enable Terna to effectively transform its business processes, two strategic enablers have been identified: the development of new technologies and of its people. In this regard, the Group has earmarked approximately €900 million of the total budget of €8.9 billion for expenditure on digitalisation and innovation, which will play an increasingly central part in keeping with their crucial role in enabling the ecological transition for the benefit of the entire system. This form of investment will generate value for the entire system and the market.

In addition, in order to optimise the working environment for its people, the Issuer has launched a project called NexTerna, with the aim of re-engineering its processes through the use of digital technologies and by rethinking physical workplaces. Finally, maintenance of a strong capital structure through robust cash generation will also help to support an attractive dividend policy.

Main results expected in the 2021-2025 Industrial Plan

As a result of investments in Regulated Activities, the value of the Issuer’s regulated asset base (RAB) will rise to € 21.8 billion in 2025, with a CAGR of 6 per cent. over the life of the Plan, a significant increase compared with the previous Plan. By the end of 2021, the value of the RAB will be € 16.7 billion, whilst the figure for the end of 2020 is expected to be € 16.1 billion.

Non-regulated Activities are expected to contribute a cumulative total of approximately € 450 million to the Group’s EBITDA over the life of the Plan, in return for limited capital absorption and low risk profile.

In terms of International Activities, Terna expects to invest up to €300 million in new projects over the life of the Plan and will contribute a cumulative total of over € 200 million to the Group’s EBITDA over the life of the Plan.

Terna’s financial structure will remain solid, and the Net Debt/RAB ratio will remain below 60 per cent. in the five-year period.

Sustainability objectives and targets

For what concerns Human Resources, the Group has made a further commitment to health and safety. This includes initiatives forming part of the “Delivering continuous improvement in occupational safety” programme and the launch of the “New Ways of Working” project called NexTerna. The latter sets out to transform the way we work by giving people greater responsibility and involving them more in meeting the goals and responding to the challenges indicated in the Industrial Plan.

Finally, in the environment dimension, the Group has adopted a Science-Based Target (SBT) to reduce the Group’s carbon footprint, with an initial target to be met by 2021. We continue to be committed to minimising the visual impact of electricity infrastructure on the landscape, including through the removal, over the life of the Plan, of around 500 km of power lines made obsolete by new investment in development of the grid.

Outlook

Group revenues are expected at € 3.04 billion in 2025, whilst EBITDA is expected to be € 2.21 billion, based on a CAGR of more than 4 per cent. for both indicators over the life of the Plan. In 2021, revenues are expected to grow to € 2.57 billion and EBITDA to € 1.84 billion. Consequently, Earnings Per Share (EPS) are expected at € 0.39 in 2021 and €0.49 in 2025, marking average annual growth rate of more than 5 per cent. over the life of the Plan. Investments are expected at € 9.2 billion in the period 2021- 2025, including € 1.4 billion in 2021.

156

Dividend Policy

From 2021 to 2023, the CAGR of the dividend per share (DPS) is expected at 8 per cent., based on the 2020 dividend. For 2024 and 2025, a 75 per cent. payout is expected, with a minimum guaranteed dividend equal to the 2023 dividend.

SUSTAINABILITY INITIATIVES

Terna has, since 2002, adopted a voluntary approach designed to foster the involvement of local government in an earlier stage (regional and local authorities, park authorities, etc.). Since 2015, this has been extended to include people from the communities directly affected by Terna’s plans through public meetings called “Terna incontra”. These are planned events that institute a continuous communication channel with people from the communities directly affected by new electricity infrastructure, whether a power line or a substation, in order to enter into a participatory design process.

Due to the restrictions imposed as a result of the COVID-19 pandemic, in 2020, Terna devised and implemented an innovative form of engagement based on a digital format. This consists of a new way of consulting local citizens and stakeholders, combining paper communication (leaflets and pamphlets) with digital content on the website (web pages providing digital information for online meetings) and social media (the publication of social media kits among local stakeholders and sponsored campaigns) in an integrated, coordinated manner. A total of 9 “Terna Incontra” meetings were held in 2020, including 2 in person at the beginning of the year, and 7 via digital platforms.

Terna’s commitment to the environment and biodiversity led, in 2009, to the conclusion of partnership agreements with critical stakeholders, such as leading environmental organisations, with the aim of arriving at shared solutions designed to boost the environmental sustainability of the National Transmission Grid (NTG). Growing concerns over the impact of climate change, and the accompanying focus on ecological transition initiatives, has led to further cooperation between Terna and these organisations. Terna currently has partnerships with Legambiente, the WWF and Greenpeace.

Approaches to climate change and the energy transition, within the context of this specific sector, have widened calls from numerous institutional investors for major companies to conduct an informed and full assessment of the business risks linked to ESG (environmental, social and governance) issues. Of particular importance, in terms of transparency and reporting, are the recommendations from the Task Force on Climate-related Financial Disclosures (the so called Bloomberg Task Force) regarding the publication of information on the implications of climate change for business strategies, in terms of risks and opportunities. This is considered of central importance, with regard to both the best possible allocation of investment and efforts to combat climate change. Terna has for some time now implemented these recommendations.

LEGISLATIVE AND REGULATORY FRAMEWORK

The current legislative and regulatory structure of the electricity sector is determined by the Bersani Decree (as defined above) which, transposing the Directive 1996/92/EC (hereinafter referred to as the Electricity Directive), led to the liberalisation of the electricity industry.

The Bersani Decree and the following legislation implemented under the Electricity Directive, set forth:

 the liberalisation of the production, import, export, purchase and sale of electricity on the market;

157

 that the activities of both transmission and dispatching of electric energy are reserved to the State and are carried out by Terna under a concession granted to the Italian ISO and transferred to Terna after the acquisition of the Italian ISO assets on 1 November 2005. The concession of Terna was granted on 20 April 2005 and was amended on 15 December 2010 by the Ministry of Economic Development (now the Ministry of Ecological Transition);

 that the activity of electricity distribution is carried out under the concessions issued by the Ministry of Economic Development (now the Ministry of Ecological Transition).

After the Bersani Decree, further provisions were issued in order to guarantee and strengthen the separation between the liberalised activities and the transmission and dispatching activities and in order to guarantee that the transmission and dispatching activities are carried out in an objective and non- discriminatory way without distinguishing between users or types of users.

Law Decree 239/03 converted into Law 290/03 set forth further provisions referring to the electricity sector. Moreover, the above-mentioned Decree:

 provided for integration of the ownership and management of the National Transmission Grid; and

 as of 1 July 2007, prevented companies (including Enel) operating in the production, importation, distribution and sale of electricity or natural gas, and any company controlled, directly or indirectly, by the State, operating in the above-mentioned sectors, from holding, directly or indirectly, more than 20 per cent. of the share capital of any company that both owns and manages any part of the National Transmission Grid or of the gas transmission network.

The Presidential Decree of 11 May 2004, (hereinafter the DPCM – Decreto del Presidente del Consiglio dei Ministri), implementing Law 290/03 set forth, among others, that:

 The Italian ISO was required to draft, by no later than 31 December 2004, a document named “Network transmission, dispatch, development and safety code” (hereinafter referred to as the Grid Code), which had to contain objective and non-discriminatory rules for the use of, and access to, the National Transmission Grid with respect to the transmission, dispatching and management operations of the same.

The Grid Code was approved by the Ministry of Productive Activities (currently Ministry of Economic Development) and the ARERA. The Grid Code is amended and updated in order to ensure compliance with the evolution of the legal and regulatory framework, and every modification, addition and change is subject to approval (including by acquiescence) by the Ministry of Economic Development (now the Ministry of Ecological Transition) and the ARERA according to their relevant competences.

 that, the entity resulting from integration of the ownership and management of the National Transmission Grid should be operated in an objective manner without distinguishing between users or types of users and that the relevant By-Laws should be amended (prior to the earlier of Enel losing control of Terna and the integration) to provide, among others, for the following:

○ any company operating in the production, importation, distribution, sale or transmission of electricity (or which controlled, was controlled by or was under common control with, any such company) and having a shareholding exceeding

158

5 per cent. of the shares of the resulting entity would be prohibited from voting, in the election of the resulting entity’s Directors, those shares exceeding 5 per cent. of the voting share capital in the resulting entity;

○ no person other than the Italian Government or State or local authorities (or entities controlled by any of them) was allowed to hold more than 5 per cent. of Terna’s share capital (which provision was not to be amended for at least three years from the integration). In any event, a shareholder with a shareholding, direct or indirect, of more than 5 per cent. of Terna’s share capital, would not be entitled to vote those shares exceeding the 5 per cent. threshold. However, according to Law 474/94, this limitation on holding more than 5 per cent. of Terna’s share capital did not apply in the case of a public tender offer with the purpose of acquiring the entire outstanding share capital of Terna in accordance with Articles 106 and 107 of the Italian Legislative Decree No. 58 of 24 February 1998 (TUF).

Legislative Decree 93/2011 implementing Directive 2009/72/EC (repealed by Directive 2019/944/EU with effect from 1 January 2021) concerning common rules on the internal market in electricity. set forth that:

 Terna is prevented, both directly and indirectly, from carrying out electric energy production or supply activities or from managing, even only on a temporary basis, electric energy production plants;

 within three months of the entry into force of this legislative decree, the ARERA defines and initiates the procedure pursuant to Article 10 of Directive 2009/72/EC for the certification of the national transmission system operator according to the ownership unbundling model. On the basis of this procedure the ARERA is required to adopt a certification decision on Terna.

Terna has been certified as an independent Transmission System Operator according to the “ownership unbundling” model with Resolution of ARERA 142/2013/R/eel.

Applicable legislation (the general principles and rules of administrative procedure as defined by Law 241/1990 and the Law Decree 239/2003 as modified by Law 290/2003) and the Environmental Law (Legislative Decree 3 April 2006 No. 152, further amended by Legislative Decree 104/2017) established a procedure for transmission grid development projects that should last for 180 days. Instead, the time limit is usually extended (even to two or three years) since required binding advice (in particular, the Environmental Impact Assessment) is not issued within the applicable deadline. Such delays represent a loss of revenue for Terna and sometimes raise difficulties in investment planning.

Procurement procedures are governed by the Legislative Decree 18 April 2016 No. 50, which implements Directives 2014/25/EU, 2014/24/EU and 2014/23/EU. The above-mentioned legal framework was further amended by Law Decree 56/2017 and by Law Decree 32/2019 as converted with modifications by Law 55/2019.

The Italian Government has notified the EU Commission of the Integrated National Plan for Energy and Climate (PNIEC), provided for by Regulation 2018/1999 of the European Parliament and of the Council on the Governance of the Energy Union. The PNIEC describes the current situation for each of the five dimensions of the Energy Union (energy security; the internal energy market; energy efficiency; decarbonisation; and research, innovation and competitiveness), including the energy system and greenhouse gas emissions and removals. It consequently sets the main objectives, targets and contributions for the aforementioned dimensions of the energy union, on a 2030 horizon and a 2050

159

horizon, and describes the measures and policies which the Government intends to implement to achieve them.

TARIFF SYSTEM

Revenue structure

As of 31 December 2020, the Terna Group’s total consolidated revenues amounted to Euro 2,513.5 million. The majority of these revenues (Euro 2,148.9 million) derive from activities regulated by the ARERA whereas the remainder derives from Non-Regulated and International Activities.

Regulated revenues

Regulated revenues are meant to cover the allowed costs for the transmission and dispatching services, according to rules set for a whole regulatory period in specific Resolutions, which are currently (i.e. for 2020-23, the 2nd half of the 5th regulatory period) Resoltion 568/19 for transmission and Resolution 351/07 - as subsequently amended by Resolution 574/19 – for dispatching.

There are three main categories of allowed costs: RAB remuneration, allowed depreciation and allowed operational expenditures (opex).

 RAB remuneration: it is calculated by applying the WACC to the value of the Regulatory Asset Base. The RAB is the allowed net value of investments entered into operation, it is revalued annually on the basis of the gross-fixed-investment deflator and is annually updated to account for yearly transmission investments, D&A and decommissioning. The WACC is the Weighted Average Cost of Capital, which is calculated according to criteria set by the NRA for the period 2016-21, with a mid-period review that led to the update of the WACC for 2019-21 from 5,3 per cent. (2016-18) to 5,6 per cent. (2019-21). In October 2020, ARERA published the Resolution 380/2020/R/com, launching the procedure for redetermining the WACC to be allowed from 2022 (this Resolution identifies initial general criteria, that will be further developed by the NRA in a future consultation document).

 Allowed depreciation: it is calculated on assets entered into operation, according to the regulatory useful life set by the NRA for specific asset categories and annually revalued by applying changes in the gross-fixed-investments deflator.

 Allowed opex: they are set by the NRA at the beginning of each regulatory sub-period, considering the actual annual operating costs of a reference year (i.e. 2018 actual value for the regulatory sub-period 2020-23) and on the residual portions – temporarily left to Terna – of the extra-efficiencies achieved in the preceding regulatory periods. The whole amount is revalued annually through an inflation index and reduced by an efficiency factor aimed at completing, over time, the transfer to final users of the achieved extra-efficiencies.

The main part of the regulated revenues comes from the transmission tariff (CTR), invoiced by Terna to distributors connected to the National Transmission Grid (NTG). The CTR has a dual structure, made of a power component (so called CTRP, covering the 90 per cent. of the allowed transmission costs) and an energy component (CTRE, covering the 10 per cent. of the allowed transmission costs). The CTR exposure to volumes dynamics is limited to the CTRE component; the CTRP component is not exposed to volume dynamics since the capacity driver considered in order to calculate ex ante the CTRP is the same that is considered ex post to invoice the same component to distributors.

160

Regulatory revenues also come from the dispatching tariff (DIS), remunerating Terna for the activities related to the dispatching service. The DIS tariff is invoices by Terna to the withdrawal dispatching users in proportion to the respective quantities of energy dispatched. The dispatching tariff is monomial, wholly calculated and invoiced on energy only, meaning that any difference between the energy forecast (considered to calculate the tariff) and the actual energy values (considered to invoice the tariff to the dispatching users) determines a difference between dispatching allowed costs and dispatching revenues. Such volume exposure is limited to a ±0.5 per cent. by a mitigation mechanism, where Terna is compensated for missing revenues up to 99.5 per cent. of recognised costs or returns the revenues exceeding 100.5 per cent.

Over time, ARERA introduced specific bonus and penalty schemes aimed at encouraging service improvement, for example in terms of system development, technical reliability and cost efficiency, moving from an input-based approach to an output-based approach.

Regarding output-based incentives, in 2018 the Authority published two Resolutions:  Resolution n. 129/2018, setting an incentive to increase transmission capacity across borders and market zones up to pre-defined targets; and  Resolution n. 699/2018, setting a further incentive mechanism aimed at solving network constraints such as bottlenecks within market zones, network constraints for voltage regulation and must-run power plants.

Moreover, at the end of 2019, through Resolution 567/2019 the Authority approved additional Output Based incentive mechanisms for the transmission service:  a cost efficiency incentive: allowing an additional premium for inter-zonal projects, if the cost is lower than the reference unit cost per section; and  a one-off bonus for the unification of ownership of the National Transmission Grid (NTG), in order to promote the acquisition by Terna of network portions of other NTG Holders, in the period 2020-2022.

Regulation also set an incentive mechanism for improving the quality of the transmission service. The incentive mechanism is based on the so-called “ENSR”, which is the reference energy not supplied KPI. The ENSR target is subject to an annual improvement and according to the ex post performance (ENSR KPI vs ENSR target) Terna may incur in a penalty or get a premium, within a cap and floor range equal to Euro -12/+30 million per year.Referring to the quality of the transmission service, regulation also foresees a “mitigation mechanism” for services provided by distribution companies: some specific types of power outage or voltage asymmetry conditions which affect VHV/MV or HV/MV transformation plants directly connected to the NTG may give rise to mitigation services supplied by the distribution companies; such services are paid by Terna up to caps set both for single outage and for the yearly total amount. Moreover, in specific situations and up to caps set in the regulation, Terna may share penalties/refunds applied to distribution companies when outages under Terna’s responsibility occur affecting customers connected to MV and LV distribution networks and such outages come from not complying with the specific standards established by the Authority (in terms of duration/number of outages). Terna’s share for exceeding the outage duration standards has a maximum annual limit of Euro 70 million (if exceeded, Terna may request that the Authority provides reimbursement of the amount exceeding the cap). Terna’s share for exceeding the standards on the number of outages is limited according to the provisions of the distribution service quality regulation. In certain specific cases, Terna may request the “Fund for Exceptional Events, Resilience and other special project” to refund such payments.

Pass-through items

In addition to regulated revenues and those generated by non-regulated activities, Terna manages cost and revenue items connected to the transactions, completed with electricity market operators, to buy

161

and sell the energy necessary for the dispatching services: these are the “pass through” items, i.e. those which do not influence net income on the Terna Group’s Income Statement (revenues equal costs).

These items include payments such as the capacity payment which Terna collects from withdrawal dispatching users and passes on to the producers who make the capacity available on the market. It also includes the payment that Terna collects from the withdrawal dispatching users and passes on to the operators which supply the load interruption service.

A significant proportion of pass-through items consist of uplift, a tariff component which includes various system costs, including covering the net expenses incurred to procure resources on the Dispatching Service Market (DSM).

In 2020, pass-through revenues and costs for the Terna Group totalled Euro 5,504,4 million. The components of these transactions are detailed in the Terna Annual Report 2020.

ISSUER’S SECURITY

The electric grid may be affected by a variety of external threats and the system operation may experience several vulnerabilities. In order to keep a high level of security for its critical infrastructures, Terna adopts advanced solutions in terms of dedicated organization, suitable systems infrastructures and internal processes as well as procedures aimed at preventing and managing critical scenarios.

In particular, the implemented security measures are aimed at protecting the company’s infrastructures as well as at promoting actions focused on the prevention and management of specific risks, such as fraud risks, information security risks in line with the objectives set out in Terna’s mission.

Physical Security

The physical security of substations is assured by using devices, systems and units operating 24 hours a day, seven days a week. To safeguard the security of the Issuer’s premises and plant, Terna has also developed a surveillance platform called the Integrated Physical Security System for Terna Substations, which allows the dedicated surveillance centre – the Security Operations Centre or SOC – to continuously monitor (VideoBox) any intrusion alarms and video from 265 substations.

Terna has partnered with the Italy’s Carabinieri police force to further strengthen its new communications and rapid intervention system, which enables the SOC to quickly alert the police in the event of attempts at forced entry to critical substations, all equipped with video surveillance equipment. The new system has been called “O.D.I.N.O.” (Operational Device for Information, Networking and Observation) and is connected, via a secure link, to the centralised operating system used by Carabinieri operations rooms throughout Italy.

In 2019 the Advanced Enterprise Protection System (SETA) was released. SETA aims to provide an integrated, georeferenced system for managing business threats and emergencies, based on a single infrastructure available to the SOC. SETA will be made available to senior management and the Company’s key departments.

On 7 January 2021, in the presence of the Commander General of the Carabinieri, General Giovanni Nistri, and Terna’s Chief Executive Officer, Stefano Antonio Donnarumma, an agreement was signed between the Carabinieri and Terna, aimed at further boosting physical protection of Italy’s strategic electricity infrastructure. Terna will supply an additional 675 state-of-the-art devices to the units directly involved in monitoring the infrastructure.

162

RISK MANAGEMENT

Terna's risk management is conducted according to a process that is widespread in the organization and that provides for the systematic and iterated risks’ identification, evaluation, treatment and monitoring. Terna's risk management model is inspired and referred to the best existing practices such as, for example, the international reference model Enterprise Risk Management (ERM), issued by the Committee of Sponsoring Organizations of the Treadway Commission (CoSO), then applied and customized to Terna business and organization.

This model is periodically reviewed and continuously improved to respond to internal changes, as well as to changes in the external context (also taking into consideration emerging risks) and best practices.

The application of the risk management model is structured and executed through a systemic approach. It integrates in the organization the three control levels required by Corporate Governance Code, each with different objectives and responsibilities. In addition, the Group implements procedures and processes aimed at coordinating the activities of the second and third level control structures, minimizing duplication of activities and maximizing the efficiency of the Internal Control and Risk Management System.The phases of risk management (identification, evaluation, treatment and monitoring of risks) take place according to a cyclical improvement process which involves reviewing, planning and implementing actions. Starting from company’s objectives (divided into strategic and recurring ones), risks are identified in order to consider potential risky events which could affect the achievement of the objectives themselves. Each event is then assessed according to Terna's risk assessment methodology and the risk management strategy is defined for each significant risk, identifying any specific actions required and the relative implementation timelines.

This cyclic process is executed every year in Terna through two different approaches that cover the entire company perimeter: Top-Down approach and Bottom-Up one. Top-Down approach is focused on the main risks that could compromise the achievement of the Group's objectives. The Bottom-Up is focused on risks related to business processes.

Risk analysis results are collected in different periodic reports made available to the Management and to the Board of Directors. Information on the Risk Management System and the main findings of the Risk Analysis and Management are also reported in the Management Report (financial statements).

Management Systems

Terna and its subsidiaries TRI S.p.A., Terna Plus, Terna Energy Solution, and Terna Crna Gora have adopted an integrated management system that acts as the main management system for all five companies.

The Management Systems Department ensures the implementation of all activities relating to its certified management system and the processes involved according to the UNI EN ISO 9001: 2015 (Quality Management System), UNI EN ISO 14001: 2015 (System of Environmental Management), UNI EN ISO 45001: 2018 (ISO standard health and safety management system), and BS Standard OHSAS 18001: 2007 (BS standard health and safety management system), UNI CEI EN ISO 37001: 2016 ( Anti-corruption management systems, obtained in 2017 as the first

163

company in Italy; Terna Crna Gora isn’t certificated), and UNI CEI EN ISO 50001: 2018 (Energy Management System).

The Energy Manager of the 4 companies is carrying out an energy management project including the completion of the “Initial Energy Review”, which takes into account the energy needs of both power stations and office buildings.

As regards the Information Security Management System, the certification obtained, according to the UNI CEI ISO / IEC 27001: 2013 standard, is limited to the processes relating to the information relating to the TIMM "Integrated Market Monitoring Text".

Furthermore, in June 2018 Terna and its subsidiary TRI S.p.A. have obtained the Management System Certification according to ISO 55001: 2014 (Asset Management Systems) for tangible assets (power lines and stations).

The testing and calibration laboratories and equipment of the company TRI S.p.A. are accredited according to the ISO 17025: 2018 standard.

The Management Systems Department takes care of the SOA certifications (attestation for participation in public tenders) of the companies Terna, TRI S.p.A., Terna Plus and Terna Solutions.

The Management Systems Structure liaises with the Italian National Accreditation Body (Accredia) for the ISO / IEC 17025 accreditations of laboratories, and with the Certification Body (IMQ SpA). For the other ISO certifications, it organizes and carries out internal audits of the management system, checks action plans and supports top management in evaluating the opportunity for new certifications and accreditations.

Business Reputation Intelligence

Terna recognises that fraud management and the analysis of the counterparties’ risk represent an essential part of its corporate management and it has implemented a fraud control system in order to improve its corporate security. Considering fraud management as a continuous process, Terna has introduced management tools and prevention measures monitoring, on a daily basis, the effectiveness of the strategies as well as the controls implemented.

In particular, with regard to Terna Group’s international transactions, Terna Group (i) has developed, adopted and updated on 13 May 2020 an internal compliance policy (the Trade Compliance Policy) setting out sanctions compliance procedures, granting the relevant disclosure to its own personnel and implementing training programmes and (ii) is carrying out due diligence activities on an ongoing basis in order to verify and detect in advance whether any contemplated transaction could violate Sanctions, thereby minimising the risk that any such violation will occur in connection with future transactions.

Moreover, as mentioned in the risk factor “Risks associated with Terna Group’s transactions involving Countries and Activities targeted by Sanctions”, some of the Sanctionable Transactions and Activities of the Terna Group are potentially exposed to the risk to be targeted by applicable Sanctions. For this reason, Terna has also hired several external consultants to enhance continuous due diligence processes (the Processes) on a subjective and objective basis on the Sanctionable Transactions and the Activities. The Processes have been, are and will be, carried out from a worldwide regulatory perspective, with particular focus from a European Union, United States and United Nations perspective. The Processes constantly provide Terna with updates on worldwide regulatory framework and with a view to determining whether no penalty for a Sanctions violation can result from any Sanctionable Transaction and/or the Activities, considering that the framework of potentially relevant Sanctions is complex, still evolving and may not be consistent across jurisdictions.

164

In this context, inter alia, the analysis has concerned the Sanctionable Transactions of Tamini Group, including sales, either directly or indirectly through third parties, of transformers (and, in certain cases, reactors, spare parts and related maintenance and/or repair services) to various end-users for installation mainly in steel manufacturing plants and electric utilities also located in many foreign countries (currently in particular Belarus, Cuba, Iraq, Libya, Moldova, Russia, Ukraine, China, in the past also Democratic Republic of Congo, Egypt, Iran, Tunisia, Venezuela and Zimbabwe). In this regard, for the first quarter of 2021, the amount of revenues generated by the Tamini Group and derived from Sanctionable Transactions was less than 0.5 per cent. of the consolidated revenues of the Terna Group.

Following the acquisition of Brugg Kabel by Terna through its subsidiary Terna Energy Solutions on 29 February 2020, the Fraud Management Unit has also carried out an overall subjective due diligence of all the counterparties of the Brugg Kabel Group. In this context the Fraud Management Unit has verified about 400 counterparty companies with the collaboration of specialized consultants, in order to monitor not to enter into relations with subjects or entities targeted by Sanctions. It is worth noting that this process has been carried out even though Brugg Kabel–as parent company of the Brugg Kabel Group until 31 March 2021 date when the Brugg Kabel Group faced a corporate reorganization – already had its own internal regulation and guidelines on export controls and international sanctions, according to its own national rules (State Secretariat for Economic Affairs – SECO).

The fraud management and the analysis of the counterparties’ risk, previously carried out by the Fraud Management Unit, are currently conducted by the Business Reputation Intelligence Department of Terna. In particular, it is noted that the Business Reputation Intelligence Department is nowadays composed by both the Fraud Management Unit and the Counterparty Due Diligence Unit.

The activities of the Business Reputation Intelligence Department consist of:

 tools and management facts analysis aimed at identifying critical areas of potential frauds;

 definition of monitoring and control procedures in order to define standards and management tools for maximising effectiveness and efficiency and for preventing misconduct;

 continuous monitoring of the efficiency of the prevention measures in place;

 implementation of protocols with Institutions in order to prevent attempts of criminal infiltration, transmitting data, information and news about contracting and subcontracting firms; and

 implementation of the Trade Compliance Policy and development of the due diligence activities, on an ongoing basis, on any transaction.

Management of Supplier Risk

In order to manage the supplier risk, Terna uses a Supplier Qualification System, set up pursuant to the related EU directives (Legislative Decree 50 of 18 April 2016 “Public contracts code for the supply of works, services and goods”), for all the main core categories of goods, works and services that Terna intends to procure, established on the basis of strategic importance, degree of competitiveness and annual procurement volumes.

Information and Cyber Security Risk

Terna has an Information Security Governance Model which enables to identify and manage the most significant cyber risks. It is based on policies and procedures, combined with a coordinated Information Risk Management operating programme, led and coordinated by the Group’s CISO (Chief Information Security Officer).

165

Since 2018, the framework for the security measures, based on Cyber Security by Design principles, used to mitigate this risk was updated to Revision 5 of the NIST 800.53 standard, thus ensuring alignment with best international practices. A pilot project involving Cyber Risk Quantitative Analysis was also completed. This was used to survey the market prices quoted by insurance brokers for Cyber Risk Assurance policies for certain forms of cyber risk.

In addition, Terna’s Computer Emergency Readiness Team (CERT) was sued to implement a structured process for identifying and rapidly containing security breaches, minimising any data loss and working to restore the affected services.

In addition to the above, following an innovative approach to risk reduction policies, Terna cooperates with Cyber Security institutional partners (national and international regulatory bodies and authorities) with which to share the risks resulting from its activities. These include include CSIRT Italia (Computer Security Incident Response Team – Italia) and CNAIPIC (the National Centre for Combating Cyber Crime and for the Protection of Critical Infrastructure).

In 2020, Terna continued to focus on Cyber Defence with several projects coordinated whit an end to end approach of Cyber Security Governance, including:

 strengthening of Perimeter Defence solutions, through adoption of Technological Perimeter (IT/OT/IoT/Cloud) Defence and Protection technologies, and implementation of new security features to counter new threats;

 evolution of CERT via the boosting of monitoring, identification and incident response capabilities, in line with new cyber risk and threat intelligence scenarios;

 Cyber protection of the industrial domain (OT), through adoption of technologies and new security solutions to strengthen the capabilities of context visibility, active defence and threat identification in the industrial domain;

 IoT security, through adoption of technologies to defend against cyberattacks on Terna’s IoT infrastructure and IT system;

 design of a Cyber LAB for testing innovative cyber security solutions in a controlled security environment, and to support Terna’s cyber security awareness programme, via awareness- raising campaigns on cyber issues with a focus on simulating attacks (e.g. phishing), and related training courses for users; and

 continuous improvement of the tools and methodologies that support the Information Security Framework within Governance Risk and Compliance (GRC) end to end processes, and security assessment solutions relating to vulnerability assessments, penetration tests and red team attack initiatives.

The operational nerve centre for the management of cyber events is the Computer Emergency Readiness Team (TERNA-CERT), which from 1 January 2021 will operate, also with the activity of Cyber Active Defence, within Terna’s newly established Cyber Defence Center. TERNA-CERT provides centralised real-time monitoring of the Group’s security, and preventive and reactive monitoring of potential cyber threats.

LITIGATION AND ARBITRATION PROCEEDINGS

In the ordinary course of its business, as of 31 December 2020, the Terna Group was party to approximately 905 civil and administrative proceedings both as plaintiff and defendant as well as to seven criminal proceedings, relating in particular to deadly or serious work incidents involving

166

employees and the destruction or alteration of natural resources in protected areas. Currently, Terna is not a party to any arbitration proceeding. The principal civil and administrative proceedings to which Terna is a party fall within the categories of annulment of authorisations, annulment of ARERA decisions, annulment of acts performed by Terna as Transmission System Operator (TSO), enforcement of ARERA decisions, damage to health and requests for modification of the location or operating conditions of the Terna Group’s Grid, lawsuits related to easements, labour rights, non-payment for the performance of contract work, environmental matter, legitimacy of construction permits and plant operations, activities carried out under concession and supply contracts.

The Terna Group established a provision for disputes and litigation which, as of 31 December 2020, amounted to Euro 19.7 million (of which Euro 18.3 million for Terna). This provision does not cover the approximately 680 civil and administrative claims and proceedings brought against the Terna Group for which the damages have not been quantified or in relation to which the plaintiffs’ prospects are considered by Terna to be remote.

Due to their nature, Terna is not able to predict the ultimate outcome of the proceedings currently pending against it, some of which may be unfavourable to Terna and may require Terna itself to pay damages to the plaintiff(s), and which may generate costs for modifying parts of the Terna Group’s Grid or temporarily removing parts of the Terna Group’s Grid from service. However, Terna does not believe that a negative outcome in any of these proceedings would compromise the operation of the Terna Group’s Grid as a whole and when taken as a whole and, save as mentioned in the risk factor “Risks associated with pending legal proceedings”, Terna believes its provisions for litigation and contingent liabilities are adequate.

Terna does not expect the outcome of the pending proceedings to have, individually or as a whole, a material adverse effect on its financial position or results of operations.

DIRECTORS, SENIOR MANAGEMENT, STATUTORY AUDITORS AND EMPLOYEES

Corporate governance rules for the Italian joint-stock companies (società per azioni) like Terna, whose shares are listed on the Italian Stock Exchange, are set forth in the Italian Civil Code, TUF and implementing rules and regulations thereof and in the set of disciplinary rules of corporate governance for listed Italian companies (hereinafter referred to as the Code of Conduct).

In order to comply with the Code of Conduct, Terna’s Board of Directors has approved various amendments to the corporate governance system (described in the Report on Corporate Governance and Ownership Structure) also in line with the principles contained in the Corporate Governance Code drawn up by the Corporate Governance Committee of listed companies promoted by Borsa Italiana on July 2018 (hereinafter referred to as the Corporate Governance Code), in particular:

 a Board of Directors responsible for company management which may delegate some of its powers to an Executive Committee and/or one of its Members. As recommended by the Corporate Governance Code, Terna’s Board of Directors has set up internal committees which have proposal and advisory duties, such as the Control and Risk, Corporate Governance and Sustainability Committee, the Appointments Committee, the Remuneration Committee and the Related-Party Transactions Committee (see also below);

 a Board of Statutory Auditors responsible for monitoring: (i) that the company complies with the law, the By-laws and the principles of correct administration in performing company activities; and (ii) the adequacy of the company’s organisational structure, internal control system and administrative/accounting system as well as those of the foreign subsidiaries outside of the EU. It is also responsible for carrying out all duties assigned to the Board of Statutory Auditors by law and the code of conduct for listed companies. Pursuant to the provisions of

167

article 19 of Italian Legislative Decree 39/2010, it is the responsibility of the Board of Statutory Auditors to supervise the financial disclosure process, the efficiency of the internal control systems, of internal reviews and of risk management, the statutory audit of annual and consolidated results and the independence of the auditing company;

Control and Risk, Corporate Governance and Sustainability Committee, Remuneration Committee, Related-Party Transactions Committees and Appointments Committee

As recommended by the Code of Conduct, in 2004 Terna’s Board of Directors established an Internal Control Committee (currently named “Control and Risk, Corporate Governance and Sustainability Committee”) which is mainly responsible for assessing the adequacy of its internal control system and accounting standards as well as for the relations with External Auditors adding to the competences of the latter those relative to the system of corporate governance. It mainly advises, assists and makes proposals to Terna’s Board of Directors with respect to all such matters. The Control and Risk, Corporate Governance and Sustainability Committee is currently composed of non-Executive Directors and all of them are independent Directors.

Since 2004 Terna’s Board of Directors has also established a specific “Remuneration Committee”. The duties of Remuneration Committee have been identified in line with the provisions of the Corporate Governance Code of reference, and the methods for holding meetings are governed by the specific internal Organisational Regulations adopted by the Board of Directors on 24 January 2007 and thereafter updated on 9 November 2011 and on 19 December 2012, to comply with the provisions of the Corporate Governance Code. More specifically, the duties of the Committee are: (i) related to the remuneration policy of the Directors and Executives with strategic responsibilities; (ii) related to the proposals and opinions for the remuneration of Executive Directors and other Directors holding specific roles; (iii) related to the fixing of performance objectives linked to the variable part of this remuneration; (iv) monitoring the application of the decisions taken by the Board; and (v) verifying the effective achievement of performance targets.

In particular, on 9 November 2011, the Board of Directors approved amendments to “Terna S.p.A.’s Organizational Rules for the Remuneration Committee” adopted in order to ensure full consistency with the indications of the Corporate Governance Code. Furthermore, the provisions pertaining to the composition and responsibilities of the Remuneration Committee were updated with particular reference to: (i) the scope of responsibility of the Committee in relation to the general policy adopted for remuneration (ii) the definition of proposals for remuneration of the Executive Directors and other Directors covering particular offices as well as (iii) the setting of performance objectives associated to the variable component of said remuneration, (iv) the monitoring of the application of decisions taken by the Board of Directors, and (v) the verification of the actual achievement of performance objectives.

In the meeting held on 19 December 2012, the Board of Directors resolved on adjustments to the competences of the committees implementing the provisions of the Corporate Governance Code, approving the modifications to the related organizational regulations without changing the Members. As a result, the “Internal Control Committee”, already instituted, changed its name into “Control and Risk Committee” and took over the activities provided by the new provisions of the Corporate Governance Code. Following the renewal of the entire Board of Directors, in the meeting of 27 May 2014, with a view to continuous improvement of the corporate governance system, the Board of Directors expanded the duties of the Control and Risk Committee, adding to the latter’s duties those related to the corporate governance system and making the consequent changes to the Organisational Regulation appointing the Members in keeping with the indications of the Corporate Governance Code according to what was communicated to the market on the same date. Consequently, the “Control and

178

Risk Committee” was renamed the “Control, Risk and Corporate Governance Committee”. The responsibilities indicated were subsequently added to said Committee and the Committee was also assigned tasks relative to Sustainability. A resolution on 15 December 2016 made the consequent amendments to the Committee’s Organisational Regulations (now known as “Organisational Regulations of the Terna S.p.A. Audit and Risk, Corporate Governance and Sustainability Committee”).

During 2010, the Board of Directors created another committee having advisory and consulting tasks, formed by at least three Directors, all independent, according to the provisions of the Corporate Governance Code with the task of expressing its preliminary opinion necessary for the adoption of the “Procedure for Related Party Transactions” as established in accordance with CONSOB Regulation No. 17221 of 12 March 2010, as amended.

On 12 November 2010, the Board of Directors identified in this committee, which is completely formed by Non-Executive, independent Directors as established by the Corporate Governance Code, the body in charge of carrying out the role required by the above-mentioned regulations both for approving transactions of greater importance and those of lesser importance as indicated in Terna’s procedures. The Committee for Transactions with Related Parties is entrusted with preliminary, advisory and consulting tasks and powers for the evaluation and the decision-making in the above-mentioned Transactions with Related Parties as well as regarding possible amendment proposal to the Procedure adopted by Terna.

At present, the Related-Party Transactions Committee is composed of non-executive and independent Directors.

The composition of these Committees is in line with the provisions of the Corporate Governance Code and Code of Conduct.

Limitations on shareholding

The transfer of Terna’s shares is not subject to any restrictions other than those contained in the shareholders’ agreement signed by CDP, SGEL and SGID, last updated on 23 May 2017 and in the By- laws or as contemplated by the terms of this document. Pursuant to article 6.3 of the By-laws in force,

10 Shareholders participating in the share capital of Terna in excess of the major thresholds indicated by CONSOB Resolution n.11971/99, on the basis of the information available and CONSOB disclosures.

183

with the exception of the Italian Government or State or local authorities (or entities controlled by any of them), no one can own, for any purpose, more than 5 per cent of Terna’s share capital. A shareholder who owns, directly or indirectly, shares that in the aggregate constitute more than 5 per cent of Terna’s share capital may not exercise its vote with regards to the excess shares. If a shareholder votes its shares in violation of the By-laws, the relevant resolution of the relevant Shareholders’ Meeting may be contested if the required majority would not have been reached but for the votes attributed to such excess shares. However, the shares may be counted for the purposes of determining whether the Shareholders’ Meeting has achieved a quorum.

Pursuant to the relevant provision of the By-laws, shares that count towards the above limit include shares owned by (i) entities that are directly or indirectly controlled by the shareholder (as well as shares controlled by any of these controlled entities), (ii) fiduciaries and/or intermediary entities, (iii) affiliates of the shareholder and (iv) related persons of the shareholder. Related persons of the shareholder include legal spouses or blood relatives up to the second degree.

Pursuant to the DPCM, the By-laws were amended in order to (i) prohibit any company that is involved in the production, import, distribution, sale or transmission of electricity (or which controls, is controlled by, or is under common control with, any such company) and that owns more than 5 per cent. of the shares of Terna, from voting shares that exceed 5 per cent. of the voting share capital in the election of the Terna’s Directors and (ii) in accordance with Law Decree 31 May 1994 No. 332 converted into Law No. 474/94 (hereinafter referred to as the Privatisation Law), prohibit any person except for the Italian Government or State or local authorities (or entities controlled by any of them) from holding more than 5 per cent. of Terna’s share capital. However, according to the Privatisation Law, this limitation on shareholding does not apply in the case of a public tender offer that has the purpose of acquiring the entire outstanding share capital in accordance with articles 106 and 107 of the TUF. See also “Legislative and Regulatory Framework” above.

In order to provide a more complete information set, please note that the By-laws do not provide for multiple-vote shares (under the terms of Art. 127-sexies of TUF) or increased-vote shares (under the terms of Art.127- quinquies of TUF).

Golden powers

As a result of abrogation of the rules contained in Art. 2, paragraph 1 of the Privatisation Law on the subject of “special powers” exercisable by the Italian State (represented, to this end, by the Ministry for the Economy and Finance, irrespective of the quantity of any Terna shares held by such Ministry), which occurred with entry into force of Law Decree no. 21 of 15 March 2012, converted into law by Art. 1, paragraph 1 of Italian Law No. 56 of 11 May 2012 (the Golden Power Decree) and its implementing decrees, the clauses on the subject of “special powers” present in Terna’s By-laws ceased to have effect, and were eliminated with a resolution of Terna’s Board of Directors of 18 December 2014.

On the basis of the provisions of the Golden Power Decree, Italian Parliament in fact laid down new provisions on the special powers of the Italian Government in relation to strategic activities in the energy, transport and communications industries, in order to standardise national legislation with the legislation of the European Union, assigning the Italian Government powers of intervention to protect the lawful, essential and strategic interests of the country. The Golden Power Decree was subsequently amended taking into account as well the implementation of a common framework for direct investment screening at the European Union level and the legislative changes adopted in 2020 spring to respond to the market volatility linked to the COVID-19 outbreak.

The normative changes, in particular, were brought about by two different trends. On one hand, as a response to the financial crisis of 2008 and to the increasing international tensions, the European Union

184

adopted a common framework on foreign direct investments by way of EU Regulation no. 452/2019. Italy has already partially complied with it, issuing, in September 2019, Law Decree no. 105/2019, notwithstanding the continuing lack of the necessary implementing regulations to be adopted through specific Decrees of the President of the Council of Ministers. The common framework set forth at EU level has entered into force on October 11, 2020. On the other hand, further regulatory changes have been enacted last spring in Italy by means of Law Decree no. 23/2020, following the invitation made by the European Commission, which, in its Communication dated 26 March 2020, urged Member States “to make full use, as of now, of the control mechanisms for foreign direct investments” in order to guard against the risk of attempts to acquire strategic businesses and assets during the COVID-19 health emergency, with the consequent “loss of critical resources and technologies”).

The economic sectors/targets in/with respect to which the Italian Government may exercise its special powers pursuant to Law Decree no. 21/2012, as amended, are: (i) defence and national security (art. 1 of Law Decree no. 21/2012); (ii) electronic broadband communication services based on 5G technology (art. 1-bis of Law Decree no. 21/2012); (iii) energy, transport and communications (art. 2 of Law Decree no. 21/2012); and (iv) the economic sectors/targets listed in art. 4 of EU Regulation no. 452/2019 to which art. 2, para. 1-ter, of Law Decree no. 21/2012 refers since its amendment through Law Decree no. 105/201911.

For the purpose of applying the “golden powers” regulation, criteria to identify relevant targets have been further defined by specific implementation decrees (so called D.P.C.M.) for some of the sectors mentioned above (e.g. that is the case in the defence and national security sectors, as well as in the energy, transport and communication sectors). For the sectors lastly included by Law Decree no. 105/2019 (i.e. critical infrastructures, critical technologies and the other sectors included by reference to art. 4 of EU Regulation no. 452/2019) this has been done recently.

Indeed, on 30 December 2020 two decrees of the President of the Council of ministers identifying (i) the assets and relationships of national interest in the sectors mentioned by art. 4 of EU Regulation no. 452/2019 (D.P.C.M. no. 179/2020) and (ii) the relevant assets in the energy, transport and communication sectors (D.P.C.M. no. 180/2020) were published in the Official Gazette. Both the decrees entered into force on 14 January 2021.

On one side, the decree no. 179/2020 identifies for the first time the assets and the capital relationships deemed as strategic in the so called “European” sectors to which the “Golden Powers” rules have been recently extended by Law Decree no. 23/2020. It is worth noting that among the main sectors affected by the newly enacted implementing regulation are: (i) energy, (ii) water, (iii) health, (iv) treatment, storage, access and control of sensitive data and information, (v) electoral infrastructure, (vi) finance, including credit and insurance, and financial market infrastructure, (vii) artificial intelligence, robotics, semiconductors, cybersecurity, nanotechnologies and biotechnologies, (viii) non-military aerospace infrastructure and technologies, and (ix) supply of critical input and food security, (x) dual use items, (xi) freedom and pluralism of the media.

11 That is, the Italian Government also considers potential effects by investment on: a) “critical infrastructures, whether physical or virtual, including energy, transport, water, health, communications, media, data processing or storage, aerospace, defense, electoral or financial infrastructures, and sensitive infrastructures, as well as land and real estate crucial for the use of such infrastructure”; b) “critical technologies and dual-use items (...) including artificial intelligence, robotics, semiconductors, cybersecurity, aerospace, defence, energy storage, quantum and nuclear technologies as well as nanotechnologies and biotechnologies”; c) “supply of critical inputs including energy or raw materials, as well as food security”; d) “access to sensitive information, including personal data, or the ability to control sensitive information”; e) “the freedom and pluralism of the media”.

185

On the other side, Decree no. 180/2020 updates the implementing regulation laid out by Presidential Decree no. 85/201412 as to the identification of relevant assets in the network industries, whose discipline is almost entirely reiterated with some minor modifications.

With reference to the recently approved implementing decrees, it is worth highlighting the following:

a) The assets described are identified in those new sectors mentioned by EU Regulation in addition to the relevant assets already described in the implementing decrees of the “Golden Powers” rules. With specific reference to energy sector, the assets listed under Decree no. 179/2020 are additional to those identified by Decree no. 180/2020. More specifically, the following assets are deemed to be relevant: critical infrastructure hosting fuels, nuclear materials or radioactive waste (including the properties, the technologies and the infrastructure involved in the management and transportation cycle of these material and waste); coastal storage of petroleum and natural gas storage infrastructures having a certain capacity; some oil pipelines; critical technologies for the management of the wholesale market of natural gas and electricity. It is also identified a residual category, characterized by the co-existence of two quantitative thresholds: reference is made to the strategic economic activities carried out in the energy sector by companies having a net yearly turnover of at least Euro 300,000,000.00 and a yearly average number of employees equal, at least, to 250 units.

b) Some exclusions from the concrete scope of application of the regulation and from the possibility to exercise the special powers of the Italian Government are set forth by the Decree No. 179/2020 under scrutiny: in particular, it is worth mentioning (i) a specific sectorial regulation in cases where there is a specific concession or privilege granted to private companies which may derive from the agreements between public authorities and private companies, as well as (ii) certain intra-group transactions. Notwithstanding a regulatory choice that takes into account the existence of lower risks, even in these events, the relevant transactions will still have to be notified in accordance with the timing and modalities governed by Law Decree no. 21/2012.

c) D.P.C.M. no. 179/2020 outlines the scope of application of the regulation on the special powers of the State through the definition of “critical infrastructures”, “critical technologies”, “critical production factors”, “critical information” and “strategic relationships”. The common denominator of these concepts is their essential nature for the maintaining of the vital functions of the society, the health, the safety and the economic and social wellbeing of the population.

d) With reference to the most notable innovations to the existing legal framework brought about by the D.P.C.M. no. 180/2020 in the network industries, having separately identified the relevant assets for the energy sector in the energy networks of national interest and in the relating agreements (i.e., agreements between public authorities and private companies related to energy networks of national interest), as specified by the decree itself, the decree at hand includes also the fundamental real estate properties needed to use the strategic networks and infrastructures. These properties are identified in light of the existence of a clear functionality link. Relevant assets pursuant to Art. 1 of decree no. 180/2020 include: (a) national natural gas transportation network and related compression stations and dispatching centers, as identified pursuant to Article 9 of Legislative Decree No. 164 of May 23, 2000, as well as gas storage facilities; (b) electricity and gas supply infrastructure from other States, including onshore and offshore LNG regasification plants; (c) national electricity transmission grid and related control and dispatching facilities; (d) management activities and key properties related to the use of the networks and infrastructures referred to in letters (a), (b) and (c) above.

12 It ceased to be effective when the implementing decree. no. 180/2020 entered into force on January 14, 2021.

186

e) Art. 2 of D.P.C.M. no. 180/2020 identifies the strategic networks and plants in the transport sector, namely the major networks and plants of national interest that are functional to ensure the most important trans-European connections (and the relating agreements). In addition to the existing regulatory framework, the new decree lists among the relevant assets also the national spaceports (in accordance with the governmental policies on “space economy”), the interports of national relevance and the road and highway network of national interest.

With respect to the scope of “golden power” regulations, it should be noted that the provisions introduced by Article 15 of Law Decree no. 23/2020 strengthened the enforceability and expanded the scope of the special powers granted to the Italian Government on foreign investments, making fully effective the extension of the scope of the “golden powers” in line with the EU Regulation. Law Decree no. 23/2020 has, in fact, introduced some temporary provisions aimed at preventing that the adverse economic situation, linked to the ongoing COVID-19 health emergency, allows predatory acquisitions in strategic European sectors. Nonetheless, it also introduced some permanent measures. The time limit for the temporary provisions originally set by Law Decree no. 23/2020 on 31st December 2020, has been extended several times by the Italian Parliament and is now set on 31 December 2021.

In particular, the main temporary provisions in force until 31 December 2021 can be summarized as follows:

a) Companies holding assets or with relationships relating to the sectors listed in para. 1 of art. 4 of EU Regulation no. 452/2019 are required to make a filing to the Presidency of the Council of Ministers also in the event of acts, resolutions or transactions implying a change in ownership, control or availability of relevant assets; b) The scope of relevant acquisitions of equity stakes in companies that are active in the sectors listed in para. 1 of art. 4 of EU Regulation no. 452/2019 have been extended in order to comprise any acquisition by foreign entities (both EU and non-EU entities) of controlling interests in companies owning any relevant asset, if such equity investment(s) imply a “stable position” of the purchaser, due to its control of the company; c) Furthermore, non-EU entities are required to make a filing to the Presidency of the Council of Ministers in relation to any acquisition of interests in companies owning any relevant asset in the sectors listed in para. 1 of art. 4 of EU Regulation no. 452/2019 “which grant voting rights or a portion of the corporate capital of at least 10 per cent, taking into account shares or quotas already directly or indirectly held and whose overall investment value is equal to or higher than Euro 1 Million”, or those resulting “in the exceeding of 15 per cent, 20 per cent, 25 per cent or 50 per cent thresholds”.

In order to allow the Italian Government to evaluate whether to exercise or not the special powers under Law Decree no. 21/2012, the companies operating in the strategic sectors listed above are required to make a filing to the Presidency of the Council of Ministers in connection with the occurrence of specific events. The filing duties (and the events triggering them) may vary depending on the specific sector under consideration: therefore, a detailed overview can be provided only on a case by case basis. This being said, it is worth highlighting that filing undertakings are generally triggered by (each action including items (i) and (ii) below, a Relevant Action):

a) any resolution, action or transaction to be adopted or carried out by the shareholders’ meetings or by the board of a company resulting in the loss of ownership, control or availability of the relevant assets that pertain to one of the strategic sectors mentioned above. This includes – but is not limited to – resolutions of the shareholders’ meeting or of the board of directors

187

concerning mergers or de-mergers, the transfer of the registered office abroad, or the transfer of a business or business unit abroad which includes any relevant assets;

b) any resolution, action or transaction to be adopted or carried out by the shareholders’ meetings or by the board of a company resulting in a change of use of the relevant assets, as well as in any change of the corporate purpose, the dissolution of the company, or else in certain amendments to the by-laws; or

c) any acquisition by non-EU entities of controlling interests in companies owning any relevant asset, if such equity investment(s) imply a stable position of the purchaser, due to its control of the company.

With specific reference to the sector of electronic broadband communication services based on 5G technology, art. 1-bis of Law Decree no. 21/2012, identifies the relevant trigger events as follows:

(i) the signing of contracts or agreements having as their object the acquisition, for any cause, of goods or services relating to the design, construction, maintenance and management of networks connected to the services when implemented with non-EU parties; (ii) the acquisition by non-EU parties, for any cause, of technology-intensive components used for the aforesaid construction or management.

To this end, elements indicating the presence of vulnerability factors that could compromise the integrity and security of the networks and data passing through them, including those identified on the basis of the principles and guidelines developed at international level and by the European Union, shall also be subject to assessment.

The filings shall be made to the Presidency of the Council of Ministers respectively by the company losing ownership, availability or control of the relevant assets or otherwise implementing a Relevant Action as well as by the purchaser (in case the Relevant Action is an acquisition) within 10 (ten) days from the adoption of the relevant resolution on the Relevant Action by the company or the implementation of the acquisition.

The decision concerning the exercise of the special powers shall be communicated, by the Italian Government, within 45 (fortyfive) days starting from the receipt of the above mentioned notification (or from the day the Government received all information it may request). Moreover, in connection with the aforementioned common framework at EU level, art. 2-ter of the Law Decree no. 21/2012 that has been newly introduced by Law Decree no. 105/2019, provides a specific cause for suspension if other EU Member States or the EU Commission intend to render, respectively, their comments or its opinion on investments undergoing screening under the Italian “golden powers” regulation (EU Regulation no. 452/2019 provides for cooperation mechanisms aimed at strengthening the effectiveness of foreign direct investments screening regulations in the EU states).

The filing imposes a “standstill effect” on the Relevant Action. In other words, pending the notification, (i) the effectiveness of any Relevant Action (other than an acquisition of shares in a relevant company) is suspended, and (ii) in case of an acquisition of shares in a relevant company, the administrative rights (such as voting and information rights) relating to such shares are suspended.The filing does produce a standstill effect on the Relevant Action itself which will be fully effective only once the 45-days term is expired or the competent authority has given its clearance on the Relevant Action. However, once the 45-days term has elapsed, the Relevant Action may be lawfully and effectively implemented, even if the Italian Government has not expressly issued an explicit resolution yet.

Furthermore, with a view to completing the existing sanctioning mechanisms, art. 16 of Law Decree no. 23/2020, extended the powers of intervention vested to the Italian Government, granting the possibility to commence ex officio proceedings for the exercise of the “golden powers” in the event that any filing obligations provided under Law Decree 21/2012 is breached. In such cases, the term for

188

completion of the relating administrative proceeding and for exercising “golden powers” (i.e., 45-day period) runs not from the closing of the transaction, but from the end of the investigation activities aimed at assessing whether there has been a breach of the notification obligation. The announcement of ex officio proceedings to the parties involved has the same standstill effect as the filing. In addition, the authority may impose sanctions for the breach of the filing obligation.

Should the Italian Government see a threat to the essential interests of the country in the relevant sector, it is entitled to exercise the following special powers: (i) the power to exercise a veto on the Relevant Action in question, thus prohibiting its consummation; and (ii) the power to impose specific conditions or prescriptions (in particular, conditions concerning the security of supplies, the security of information, the technological transfers, etc.). The Government enjoys a great degree of discretion in identifying specific conditions and prescriptions.

The breach of the “golden powers” regulation (reference is made to both failure to notify in time and failure to comply with the measures taken by the Italian Government) potentially gives rise to heavy sanctions. More specifically, the sanctions entail both civil and administrative consequences: a) Civil sanctions: Relevant Actions adopted or implemented in breach of the “golden powers” provisions are null and void (similarly, any resolutions adopted with the decisive vote of the shares acquired as a consequence of the implementation of a Relevant Action are null and void). The Government may also invite the companies involved and any counterparty to reinstate the previous situation at their own expense; b) Administrative sanctions: a pecuniary administrative fine up to double the value of the relevant transaction (maximum amount) and, in any case, not less than 1 per cent. of the cumulative turnover realized by the involved companies in the last fiscal year (minimum amount). Please note that with specific reference to the sector of electronic broadband communication services based on 5G technology, failure to comply with notification duties or with the Government prescriptions is subject to an administrative fine up to the 150 per cent. of the value of the transaction and in any case no less than 25 per cent. of such value.

The procedures for notifications and for activating the “special powers” are regulated by specific decrees, containing rules on coordination activities of the Prime Minister’s Office preparatory to the exercise of special powers.

TAXATION

The statements herein regarding taxation are based on the laws in force in Italy, in the European Union and in Luxembourg as at the date of this Base Prospectus and are subject to any changes in law occurring after such date, which changes could be made on a retroactive basis. The following summary does not purport to be a comprehensive description of all the tax considerations which may be relevant to a decision to subscribe for, purchase, own or dispose of the Notes and does not purport to deal with the tax consequences applicable to all categories of investors, some of which (such as dealers in securities or commodities) may be subject to special rules. Prospective purchasers of the Notes are advised to consult their own tax advisers concerning the overall tax consequences of their ownership of the Notes. ITALIAN TAXATION Tax treatment of the Notes Legislative Decree No. 239 of 1 April 1996, as subsequently amended, (Decree 239) provides for the applicable regime with respect to the tax treatment of interest, premium and other income (including the difference between the redemption amount and the issue price) from notes issued, inter alia, by Italian listed companies, falling within the category of bonds (obbligazioni) or debentures similar to bonds (titoli similari alle obbligazioni) issued, inter alia, by Italian companies with shares traded on a regulated market or multilateral trading facility of an EU or EEA Member State which exchanges information with the Italian tax authorities. For this purpose, debentures similar to bonds are securities that incorporate an unconditional obligation to pay, at maturity, an amount not lower than their nominal value and which do not grant the holder any direct or indirect right of participation to (or control of) the management of the Issuer.

Italian resident Noteholders

Where an Italian resident Noteholder is: (a) an individual not engaged in an entrepreneurial activity to which the Notes are connected (unless he has opted for the application of the risparmio gestito regime - see under “Capital gains tax” below); (b) a non-commercial partnership; (c) a non-commercial private or public institution; or (d) an investor exempt from Italian corporate income taxation, interest, premium and other income relating to the Notes (hereinafter collectively referred to as Interest), are subject to a withholding tax, referred to as “imposta sostitutiva”, levied at the rate of 26 per cent. In the event that the Noteholders described under (a) and (c) above are engaged in an entrepreneurial activity to which the Notes are connected, the imposta sostitutiva applies as a provisional tax. Subject to certain limitations and requirements (including a minimum holding period), Italian resident individuals not acting in connection with an entrepreneurial activity or social security entities pursuant to Legislative Decree No. 509 of 30 June 1994 and Legislative Decree No. 103 of 10 February 1996 may be exempt from any income taxation, including the imposta sostitutiva, on Interest relating to the Notes if the Notes are included in a long-term savings account (piano di risparmio a lungo termine) that meets the requirements set forth under Italian tax law. Where an Italian resident Noteholder is a company or similar commercial entity, a commercial partnership, or a permanent establishment in Italy of a foreign company to which the Notes are effectively connected, and the Notes are deposited with an authorised intermediary Interest from the Notes will not be subject to imposta sostitutiva, but must be included in the relevant Noteholder’s income tax return and are therefore subject to general Italian corporate taxation (IRES) (and, in certain circumstances, depending on the “status” of the Noteholder, also to the regional tax on productive activities (IRAP)). Where an Italian resident Noteholder is an individual engaged in an entrepreneurial activity to which the Notes are connected, Interest relating to the Notes is subject to imposta sostitutiva and will be included its relevant income tax return. As a consequence, such Interest will be subject to the ordinary income tax and the imposta sostitutiva may be recovered as a deduction from the income tax due.

190

Under the current regime provided by Law Decree No. 351 of 25 September 2001, converted into Law No. 410 of 23 November 2001 (Decree 351), Article 32 of Law Decree No. 78 of 31 May 2010, converted into Law No. 122 of 30 July 2010 and Legislative Decree No. 44 of 4 March 2014, all as amended, Italian real estate investment funds created under Article 37 of Legislative Decree No. 58 of 24 February 1998, as amended and supplemented, and Article 14-bis of Law No. 86 of 25 January 1994 and Italian real estate SICAFs (the Real Estate SICAFs) are subject neither to imposta sostitutiva nor to any other income tax in the hands of the real estate investment fund or the Real Estate SICAF provided that the fund or the Real Estate Fund is the beneficial owner of the payments under the Notes and the Notes are deposited with an authorised intermediary. If the investor is resident in Italy and is an open-ended or closed-ended investment fund, a SICAF (an Italian investment company with fixed share capital), other than a Real Estate SICAF, or a SICAV (an investment company with variable capital) established in Italy (together, the Fund) and either (i) the Fund or (ii) its manager is subject to the supervision of a regulatory authority, and the relevant Notes are held by an authorised intermediary, as clarified by the Italian tax authorities through Circular No. 11/E of 28 March 2012, Interest accrued during the holding period on such Notes will not be subject to imposta sostitutiva, but must be included in the management results of the Fund. The Fund will not be subject to taxation on such results but a withholding tax of 26 per cent. will apply, in certain circumstances, to distributions made in favour of unitholders or shareholders (the Collective Investment Fund Tax). Where an Italian resident Noteholder is a pension fund (subject to the regime provided for by article 17 of the Legislative Decree No. 252 of 5 December 2005 – the Pension Fund) and the Notes are deposited with an authorised intermediary, Interest relating to the Notes and accrued during the holding period will not be subject to imposta sostitutiva, but must be included in the result of the relevant portfolio accrued at the end of the tax period, to be subject to a 20 per cent. substitute tax. Subject to certain conditions (including minimum holding period requirement) and limitations, Interest relating to the Notes may be excluded from the taxable base of the 20 per cent. substitute tax if the Notes are included in a long-term individual savings account (piano di risparmio a lungo termine) that meets the requirements set forth under Italian tax law.. Pursuant to Decree 239, imposta sostitutiva is applied by banks, società di intermediazione mobiliare (SIMs), fiduciary companies, società di gestione del risparmio (SGRs), stockbrokers and other entities identified by a decree of the Ministry of Finance (each an Intermediary). An Intermediary must: (a) be (i) resident in Italy or (ii) be a permanent establishment in Italy of a non- Italian resident financial intermediary or (iii) an entity or company not resident in Italy, acting through a system of centralised administration of notes and directly connected with the Department of Revenue of the Italian Ministry of Finance having appointed an Italian representative for the purposes of Decree 239; and (b) intervene, in any way, in the collection of Interest or in the transfer of the Notes. For the purpose of the application of the imposta sostitutiva, a transfer of Notes includes any assignment or other act, either with or without consideration, which results in a change of the ownership of the relevant Notes or in a change of the Intermediary with which the Notes are deposited. Where the Notes are not deposited with an Intermediary, the imposta sostitutiva is applied and withheld by any entity paying interest to a Noteholder or, absent that, directly by the Issuer paying that interest.

Non-Italian resident Noteholders

Where the Noteholder is a non-Italian resident without a permanent establishment in Italy to which the Notes are connected, an exemption from the imposta sostitutiva applies provided that the non-Italian resident beneficial owner is either: (a) resident, for tax purposes, in a country which allows for a satisfactory exchange of information with Italy as listed in the Italian Ministerial Decree of 4 September 1996, as amended by Ministerial Decree of 23 March 2017 and possibly further amended by future decree issued pursuant to Article 11(4)(c) of Decree 239 (as amended by Legislative Decree No.147 of 14 September 2015) (the White List); or (b) an international entity or body set up in accordance with international agreements which have entered into force in Italy; or (c) a Central Bank or an entity which

191

manages, inter alia, the official reserves of a foreign State; or (d) an institutional investor which is resident in a country included in the White List, even if it does not possess the status of taxpayer in its own country of residence. In order to ensure gross payment, non-Italian resident Noteholders must be the beneficial owners of payments of Interest and (a) deposit, directly or indirectly, the Notes with a resident bank or SIM or a permanent establishment in Italy of a non-Italian resident bank or SIM or with a non-Italian resident entity or company participating in a centralised securities management system which is in contact, via computer, with the Ministry of Economy and Finance, and (b) file with the relevant depository, prior to or concurrently with the deposit of the Notes, a statement of the relevant Noteholder, which remains valid until withdrawn or revoked, in which the Noteholder declares to be eligible to benefit from the applicable exemption from imposta sostitutiva. Such statement, which is not requested for international bodies or entities set up in accordance with international agreements which have entered into force in Italy nor in case of foreign Central Banks or entities which manage, inter alia, the official reserves of a foreign State, must comply with the requirements set forth by Ministerial Decree of 12 December 2001, as subsequently amended. Failure of a non-Italian resident Noteholder to comply in due time with the procedures set forth in Decree No. 239 and in the relevant implementing rules will result in the application of imposta sostitutiva on Interests payments to such non resident Noteholder. The imposta sostitutiva will be applicable at the rate of 26 per cent. (or at the reduced rate provided for by the applicable double tax treaty) to Interest paid to Noteholders who are resident, for tax purposes, in countries which do not allow for a satisfactory exchange of information with Italy.

Atypical securities

Interest payments relating to Notes that are not deemed to fall within the category of bonds (obbligazioni) or debentures similar to bonds (titoli similari alle obbligazioni) may be subject to a withholding tax, levied at the rate of 26 per cent. For this purpose, debentures similar to bonds are securities that incorporate an unconditional obligation to pay, at maturity, an amount not lower than their nominal value and which do not grant the holder any direct or indirect right of participation to (or control of) the management of the Issuer. Subject to certain limitations and requirements (including a minimum holding period), Italian resident individuals not engaged in an entrepreneurial activity or social security entities pursuant to Legislative Decree No. 509 of 30 June 1994 and Legislative Decree No. 103 of 10 February 1996 may be exempt from Italian withholding tax on proceeds received under Notes classifying as atypical securities, if the Notes are included in a long-term individual savings account (piano di risparmio a lungo termine) that meets the requirements set forth under Italian tax law. Where the Noteholder is: (a) an Italian individual engaged in an entrepreneurial activity to which the Notes are connected; (b) an Italian company or a similar Italian commercial entity; (c) a permanent establishment in Italy of a; (d) an Italian commercial partnership; or (e) an Italian commercial private or public institution, such withholding tax is a provisional withholding tax. In all other cases the withholding tax is a final withholding tax. For non-Italian resident Noteholders, the withholding tax rate may be reduced by any applicable tax treaty.

Capital gains tax

Any gain obtained from the sale or redemption of the Notes would be treated as part of the taxable income (and, in certain circumstances, depending on the “status” of the Noteholder, also as part of the net value of the production for IRAP purposes) if realised by an Italian company or a similar commercial entity (including the Italian permanent establishment of foreign entities to which the Notes are connected) or Italian resident individuals engaged in an entrepreneurial activity to which the Notes are connected.

192

Where an Italian resident Noteholder is (i) an individual holding the Notes not in connection with an entrepreneurial activity, (ii) a non commercial partnership or (iii) a non-commercial private or public institution, any capital gain realised by such Noteholder from the sale or redemption of the Notes would be subject to an imposta sostitutiva, levied at the current rate of 26 per cent. Noteholders may set off losses with gains. Subject to certain limitations and requirements (including a minimum holding period), Italian resident individuals not engaged in an entrepreneurial activity or social security entities pursuant to Legislative Decree No. 509 of 30 June 1994 and Legislative Decree No. 103 of 10 February 1996 may be exempt from Italian capital gain taxes, including the imposta sostitutiva, on capital gains realised upon sale or redemption of the Notes, if the Notes are included a long-term individual savings account (piano di risparmio a lungo termine) that meets the requirements set forth under Italian tax law. In respect of the application of imposta sostitutiva, taxpayers may opt for one of the three regimes described below. Under the tax declaration regime (regime della dichiarazione), which is the default regime for Noteholders under (i) to (iii) above, the imposta sostitutiva on capital gains will be chargeable, on a cumulative basis, on all capital gains, net of any incurred capital loss, realised by the Italian resident individual Noteholder holding the Notes not in connection with an entrepreneurial activity pursuant to all sales or redemptions of the Notes carried out during any given tax year. The relevant Noteholder must indicate the overall capital gains realised in any tax year, net of any relevant incurred capital loss, in the annual tax return and pay imposta sostitutiva on such gains together with any balance income tax due for such year. Capital losses in excess of capital gains may be carried forward against capital gains realised in any of the four succeeding tax years. As an alternative to the tax declaration regime, Noteholders under (i) to (iii) above may elect to pay the imposta sostitutiva separately on capital gains realised on each sale or redemption of the Notes (the risparmio amministrato regime). Such separate taxation of capital gains is allowed subject to (a) the Notes being deposited with Italian banks, SIMs or certain authorised financial intermediaries and (b) an express election for the risparmio amministrato regime being timely made in writing by the relevant Noteholder. The depository is responsible for accounting for imposta sostitutiva in respect of capital gains realised on each sale or redemption of the Notes (as well as in respect of capital gains realised upon the revocation of its mandate), net of any incurred capital loss, and is required to pay the relevant amount to the Italian tax authorities on behalf of the taxpayer, deducting a corresponding amount from the proceeds to be credited to the Noteholder or using funds provided by the Noteholder for this purpose. Under the risparmio amministrato regime, where a sale or redemption of the Notes results in a capital loss, such loss may be deducted from capital gains subsequently realised, within the same securities management, in the same tax year or in the following tax years up to the fourth. Under the risparmio amministrato regime, the Noteholder is not required to declare the capital gains in the annual tax return. Any capital gains realised by Italian Noteholders under (i) to (iii) above who have entrusted the management of their financial assets, including the Notes, to an authorised intermediary and have opted for the so-called “risparmio gestito” regime will be included in the computation of the annual increase in value of the managed assets accrued, even if not realised, at year end, subject to a 26 per cent. substitute tax, to be paid by the managing authorised intermediary. Under the risparmio gestito regime, any depreciation of the managed assets accrued at year end may be carried forward against increase in value of the managed assets accrued in any of the four succeeding tax years. Under the risparmio gestito regime, the Noteholder is not required to declare the capital gains realised in the annual tax return. Any capital gains realised by a Noteholder who is an Italian real estate fund to which the provisions of Decree 351, Law Decree No. 78 of 31 May 2010, converted into Law No. 122 of 30 July 2010 and Legislative Decree No. 44 of 4 March 2014, all as amended, apply or a Real Estate SICAF will be subject neither to imposta sostitutiva nor to any other income tax at the level of the real estate investment fund or the Real Estate SICAF. Any capital gains realised by Noteholders which is a Fund will not be subject to imposta sostitutiva, but will be included in the management results of the Fund. Such result will not be subject to taxation at

193

the level of the Fund, but subsequent distributions in favour of unitholders of shareholders may be subject to the Collective Investment Fund Tax. Any capital gains realised by a Noteholder who is an Italian Pension Fund will be included in the result of the relevant portfolio accrued at the end of the tax period, to be subject to the 20 per cent. substitute tax. Subject to certain conditions (including minimum holding period requirement) and limitations, capital gains on the Notes may be excluded from the taxable base of the 20 per cent. substitute tax if the Notes are included in a long-term individual savings account (piano di risparmio a lungo termine) that meets the requirements set forth under Italian tax law. Capital gains realised by non-Italian-resident Noteholders, not having a permanent establishment in Italy to which the Notes are connected, from the sale or redemption of Notes issued by an Italian resident issuer, which are traded on regulated markets (and, in certain cases, subject to filing of required documentation) are neither subject to the imposta sostitutiva nor to any other Italian income tax. Capital gains realised by non-Italian resident Noteholders, not having a permanent establishment in Italy to which the Notes are connected, from the sale or redemption of Notes not traded on regulated markets are not subject to the imposta sostitutiva, provided that the effective beneficiary: (a) is resident in a country included in the White List; or (b) is an international entity or body set up in accordance with international agreements which have entered into force in Italy; or (c) is a Central Bank or an entity which manages, inter alia, the official reserves of a foreign State; or (d) is an institutional investor which is resident in a country included in the White List, even if it does not possess the status of taxpayer in its own country of residence. If none of the conditions above is met, capital gains realised by non-Italian resident Noteholders from the sale or redemption of Notes not traded on regulated markets are subject to the imposta sostitutiva at the current rate of 26 per cent. On the contrary, should the Notes be traded on regulated markets, capital gains realized by non-Italian resident Noteholders would not be subject to Italian taxation. In any event, non-Italian resident individuals or entities without a permanent establishment in Italy to which the Notes are connected that may benefit from a double taxation treaty with Italy providing that capital gains realised upon the sale or redemption of Notes are to be taxed only in the country of tax residence of the recipient, will not be subject to imposta sostitutiva in Italy on any capital gains realised upon the sale or redemption of Notes. Inheritance and gift taxes Pursuant to Law Decree No. 262 of 3 October 2006, converted with amendments into Law No. 286 of 24 November 2006, as subsequently amended, the transfers of any valuable asset (including shares, notes or other securities) as a result of death or donation are taxed as follows:

(i) transfers in favour of spouses and direct descendants or direct ancestors are subject to an inheritance and gift tax applied at a rate of 4 per cent. on the value of the inheritance or the gift exceeding, for each beneficiary, Euro 1,000,000;

(ii) transfers in favour of relatives to the fourth degree or relatives-in-law to the third degree are subject to an inheritance and gift tax at a rate of 6 per cent. on the entire value of the inheritance or the gift. Transfers in favour of brothers/sisters are subject to the 6 per cent. inheritance and gift tax on the value of the inheritance or the gift exceeding, for each beneficiary, Euro 100,000; and

(iii) any other transfer is, in principle, subject to an inheritance and gift tax applied at a rate of 8 per cent. on the entire value of the inheritance or the gift. If the transfer is made in favour of persons with severe disabilities, the tax is levied at the rate mentioned above in paragraphs (i), (ii) and (iii) above on the value exceeding, for each beneficiary, Euro 1,500,000.

194

The transfer of financial instruments (including the Notes) as a result of death is exempt from inheritance tax when such financial instruments are included in a long-term individual savings account (piano di risparmio a lungo termine) that meets the requirements set forth under Italian tax law. Transfer tax Following the repeal of the Italian transfer tax, contracts relating to the transfer of securities are subject to the following registration tax: (i) public deeds and notarised deeds are subject to fixed registration tax at a rate of €200; and (ii) private deeds are subject to registration tax only in "case of use" (caso d'uso) or in the case of "explicit reference" (enunciazione) or voluntary registration. Stamp duty Pursuant to Article 13 of the tariff attached to Presidential Decree No. 642 of 26 October 1972 (Decree 642), a proportional stamp duty applies on an annual basis to the periodic reporting communications sent by financial intermediaries to their clients for the Notes deposited in Italy. The stamp duty applies at a rate of 0.2 per cent. and cannot exceed €14,000, for taxpayers different from individuals; this stamp duty is determined on the basis of the market value or - if no market value figure is available - the nominal value or redemption amount of the Notes held. Based on the wording of the law and the implementing decree issued by the Italian Ministry of Economy on 24 May 2012, the stamp duty applies to any investor who is a client (as defined in the regulations issued by the Bank of Italy on 9 February 2011, as subsequently amended, supplemented and restated) of an entity that exercises in any form a banking, financial or insurance activity within the Italian territory. The communication is deemed to be sent to the customers at least once a year, even for instruments for which it is not mandatory. In case of reporting periods less than 12 months, the stamp duty is payable on a pro-rata basis. Wealth Tax on securities deposited abroad According to Article 19 of Decree No. 201 of 6 December 2011, as amended and supplemented, individuals, non-commercial entities and certain partnerships (società semplici or similar partnerships in accordance with Article 5 of Presidential Decree No. 917 of 22 December 1986) resident in Italy for tax purposes holding financial products – including the Notes – outside of the Italian territory are required to pay in their own annual tax declaration a wealth tax at the rate of 0.2 per cent. Pursuant to the provisions of Article 134 of Law Decree 34/2020, as converted into law with amendments by Law No. 77 of 17 July 2020, the wealth tax cannot exceed €14,000 per year for taxpayers different from individuals. This tax is calculated on the market value of the Notes at the end of the relevant year or - if no market value figure is available - the nominal value or the redemption value of such financial assets held outside the Italian territory. Taxpayers are entitled to an Italian tax credit equivalent to the amount of wealth taxes paid in the State where the financial assets are held (up to an amount equal to the Italian wealth tax due). Financial assets (including the Notes) held abroad are excluded from the scope of the wealth tax if they are administered by Italian financial intermediaries pursuant to an administration agreement. In this case, the above mentioned stamp duty provided for Article 13 of the tariff attached to Decree 642 does apply. Italian Financial Transaction Tax Italian shares and other participating instruments, as well as depository receipts representing those shares and participating instruments irrespective of the relevant issuer (cumulatively referred to as In- Scope Shares), received by a Noteholder upon physical settlement of the Notes may be subject to a per cent. Italian financial transaction tax (IFTT) calculated on the value of the Notes as determined according to Article 4 of Ministerial Decree of 21 February 2013, as amended (the IFTT Decree). Investors in certain equity-linked notes mainly having as underlying or mainly linked to In-Scope Shares, are subject to IFTT at a rate ranging between EUR 0.01875 and EUR 200 per counterparty, depending on the notional value of the relevant derivative transaction or transferable securities

195

calculated according to Article 9 of the IFTT Decree. IFTT applies upon subscription, negotiation or modification of the derivative transactions or transferable securities. The tax rate may be reduced to a fifth if the transaction is executed on certain qualifying regulated markets or multilateral trading facilities.

Tax Monitoring rules

According to the Law Decree No. 167 of 28 June 1990, converted with amendments into Law No. 227 of 4 August 1990, as amended from time to time, individuals, non-commercial entities and certain partnerships (società semplici or similar partnerships in accordance with Article 5 of Presidential Decree No. 917 of 22 December 1986) resident in Italy for tax purposes, under certain conditions, are required to report for tax monitoring purposes in their yearly income tax return the amount of investments directly or indirectly held abroad. The requirement applies also where the persons above, being not the direct holder of the financial instruments, are the actual owner of the instrument.

Furthermore, the above reporting requirement is not required to comply with respect to: (i) Notes deposited for management with qualified Italian financial intermediaries; (ii) contracts entered into through the intervention of qualified Italian financial intermediaries, upon condition that the items of income derived from the Notes have been subject to tax by the same intermediaries; or (iii) if the foreign investments are only composed by deposits and/or bank accounts and their total aggregate value does not exceed a Euro 15,000 threshold throughout the relevant year.

LUXEMBOURG TAXATION

The following information is of a general nature only and is based on the laws presently in force in Luxembourg, though it is not intended to be, nor should it be construed to be, legal or tax advice. Prospective investors in the Notes should therefore consult their own professional advisers as to the effects of state, local or foreign laws, including Luxembourg tax law, to which they may be subject.

Please be aware that the residence concept used under the respective headings below applies for Luxembourg income tax assessment purposes only. Any reference in the present section to a tax, duty, levy, impost or other charge or withholding of a similar nature refers to Luxembourg tax law and/or concepts only. Also, please note that a reference to Luxembourg income tax encompasses corporate income tax (impôt sur le revenu des collectivités), municipal business tax (impôt commercial communal), a solidarity surcharge (contribution au fonds pour l’emploi) as well as personal income tax (impôt sur le revenu) generally. Investors may further be subject to net wealth tax (impôt sur la fortune) as well as other duties, levies or taxes. Corporate income tax, municipal business tax as well as the solidarity surcharge invariably apply to most corporate taxpayers resident in Luxembourg for tax purposes. Individual taxpayers are generally subject to personal income tax and the solidarity surcharge. Under certain circumstances, where an individual taxpayer acts in the course of the management of a professional or business undertaking, municipal business tax may apply as well.

Taxation of holders of the Notes

Withholding Tax

(a) Non-resident holders of Notes

Under Luxembourg general tax laws currently in force there is no withholding tax on payments of principal, premium or interest made to non-resident holders of Notes, nor on accrued but unpaid interest in respect of the Notes, nor is any Luxembourg withholding tax payable upon redemption or repurchase of the Notes held by non-resident holders of Notes.

(b) Resident holders of Notes

196

Under Luxembourg general tax laws currently in force and subject to the law of 23 December 2005, as amended (the Law), there is no withholding tax on payments of principal, premium or interest made to Luxembourg resident holders of Notes, nor on accrued but unpaid interest in respect of Notes, nor is any Luxembourg withholding tax payable upon redemption or repurchase of Notes held by Luxembourg resident holders of Notes.

Under the Law, payments of interest or similar income made or ascribed by a paying agent established in Luxembourg to an individual beneficial owner who is a resident of Luxembourg will be subject to a withholding tax of 20 per cent. Such withholding tax will be in full discharge of income tax if the beneficial owner is an individual acting in the course of the management of his/her private wealth. Responsibility for the withholding of the tax will be assumed by the Luxembourg paying agent. Accordingly, payments of interest under the Notes coming within the scope of the Law would be subject to a withholding tax at a rate of 20 per cent.

Income Taxation

(i) Non-resident holders of Notes

A non-resident holder of the Notes, not having a permanent establishment or permanent representative in Luxembourg to which/whom such Notes are attributable, is not subject to Luxembourg income tax on interest accrued or received, redemption premiums or issue discounts, under the Notes. A gain realised by such non-resident holder of the Notes on the sale or disposal, in any form whatsoever, of the Notes is further not subject to Luxembourg income tax.

A non-resident corporate holder of Notes or an individual holder of Notes acting in the course of the management of a professional or business undertaking, that has a permanent establishment or permanent representative in Luxembourg to which/whom such Notes are attributable, is subject to Luxembourg income tax on interest accrued or received, redemption premiums or issue discounts, under the Notes and on any gains realised upon the sale or disposal, in any form whatsoever, of the Notes.

(ii) Resident holders of Notes

Holders of Notes who are residents of Luxembourg will not be liable to any Luxembourg income tax on repayment of principal.

(a) Luxembourg resident corporate holders of Notes

A corporate holder of Notes must include any interest accrued or received, any redemption premium or issue discount, as well as any gain realised on the sale or disposal, in any form whatsoever, of the Notes, in its taxable income for Luxembourg income tax assessment purposes.

A corporate holder of Notes that is governed by the law of 11 May 2007 on family estate management companies, as amended, or by the law of 13 February 2007 on specialised investment funds, as amended, or by the law of 17 December 2010 on undertakings for collective investment, as amended, or by the law of 23 July 2016 on reserved alternative investment funds and which does not fall under the special tax regime set out in article 48 thereof, is neither subject to Luxembourg income tax in respect of interest accrued or received, any redemption premium or issue discount, nor on gains realised on the sale or disposal, in any form whatsoever, of the Notes.

(b) Luxembourg resident individual holders of Notes

197

An individual holder of Notes, acting in the course of the management of his/her private wealth, is subject to Luxembourg income tax at progressive rates in respect of interest received, redemption premiums or issue discounts, under the Notes, except if (i) withholding tax has been levied on such payments in accordance with the Law or (ii) the individual holder of the Notes has opted for the application of a 20 per cent. tax in full discharge of income tax in accordance with the Law, which applies if a payment of interest has been made or ascribed by a paying agent established in a EU Member State (other than Luxembourg), or in a Member State of the European Economic Area (other than a EU Member State). A gain realised by an individual holder of Notes, acting in the course of the management of his/her private wealth, upon the sale or disposal, in any form whatsoever, of Notes is not subject to Luxembourg income tax, provided this sale or disposal took place more than six months after the Notes were acquired. However, any portion of such gain corresponding to accrued but unpaid interest income is subject to Luxembourg income tax, except if tax has been levied on such interest in accordance with the Law.

An individual holder of Notes acting in the course of management of a professional or business undertaking must include this interest in its taxable basis. If applicable, the tax levied in accordance with the Law will be credited against his/her final tax liability.

Net Wealth Taxation

A corporate holder of Notes, whether it is a resident of Luxembourg for tax purposes or, if not, it maintains a permanent establishment or a permanent representative in Luxembourg to which such Notes are attributable, is subject to Luxembourg wealth tax on such Notes, except if the holder of Notes is governed by the law of 11 May 2007 on family estate management companies, as amended, or by the law of 13 February 2007 on specialised investment funds, as amended, or by the law of 17 December 2010 on undertakings for collective investment, as amended, or by the law of 23 July 2016 on reserved alternative investment funds, or is a securitisation company governed by the law of 22 March 2004 on securitisation, as amended, or is a capital company governed by the law of 15 June 2004 on venture capital vehicles, as amended.13

An individual holder of Notes, whether he/she is a resident of Luxembourg or not, is not subject to Luxembourg wealth tax on such Notes.

Other Taxes

In principle, neither the issuance nor the transfer, repurchase or redemption of Notes will give rise to any Luxembourg registration tax, or similar taxes.

However, a fixed or ad valorem registration duty may be due upon registration of the Notes in Luxembourg in the case where the Notes are physically attached to a public deed or to any other document subject to mandatory registration, as well as in the case of a registration of the Notes on a voluntary basis.

Where a holder of Notes is a resident of Luxembourg for tax purposes at the time of his/her death, the Notes are included in his/her taxable estate for inheritance tax assessment purposes.

13 Please however note that securitisation companies governed by the law of 22 March 2004 on securitisation, as amended, or capital companies governed by the law of 15 June 2004 on venture capital vehicles, as amended, or reserved alternative investment funds governed by the law of 23 July 2016 and which fall under the special tax regime set out under article 48 thereof may, under certain conditions, be subject to minimum net wealth tax.

Gift tax may be due on a gift or donation of Notes if embodied in a Luxembourg deed or recorded in Luxembourg.

THE PROPOSED FINANCIAL TRANSACTIONS TAX (FTT)

On 14 February 2014, the European Commission published a proposal (the Commission's Proposal) for a Directive for a common FTT in Belgium, Germany, Estonia, Greece, Spain, France, Italy, Austria, Portugal, Slovenia and Slovakia (the participating Member States). However, Estonia has since stated that it will not participate.

The Commission's Proposal has very broad scope and could, if introduced in its current form, apply to certain dealings in the Notes (including secondary market transactions) in certain circumstances. The issuance and subscription of the Notes should, however, be exempt.

Under the Commission's Proposal the FTT could apply in certain circumstances to persons both within and outside of the participating Member States. Generally, it would apply to certain dealings in the Notes where at least one party is a financial institution, and at least one party is established in a participating Member State. A financial institution may be, or be deemed to be, "established" in a participating Member State in a broad range of circumstances, including (a) by transacting with a person established in a participating Member State or (b) where the financial instrument which is subject to the dealings is issued in a participating Member State.

However, the FTT proposal remains subject to negotiation between the participating Member States. It may therefore be altered prior to any implementation, the timing of which remains unclear. Additional EU Member States may decide to participate. Prospective holders of the Notes are advised to seek their own professional advice in relation to the FTT.

FOREIGN ACCOUNT TAX COMPLIANCE ACT

Pursuant to certain provisions of the U.S. Internal Revenue Code of 1986, commonly known as FATCA, withholding may be required on, among other things, (i) certain payments made by “foreign financial institutions” (“foreign passthru payments”) and (ii) dividend equivalent payments (as described below in “U.S. Dividend Equivalent Withholding”), in each case, to persons that fail to meet certain certification, reporting, or related requirements. A number of jurisdictions (including Italy) have entered into, or have agreed in substance to, intergovernmental agreements with the United States to implement FATCA (IGAs), which modify the way in which FATCA applies in their jurisdictions. Under the provisions of IGAs as currently in effect, a foreign financial institution in an IGA jurisdiction would generally not be required to withhold under FATCA or an IGA from payments that it makes.

Certain aspects of the application of the FATCA provisions and IGAs to instruments such as the Notes, including whether withholding would ever be required pursuant to FATCA or an IGA with respect to payments on instruments such as the Notes, are uncertain and may be subject to change. If withholding would be required pursuant to FATCA or an IGA with respect to foreign passthru payments, such withholding would not apply prior to the date that is two years after the date on which final regulations defining foreign passthru payments are published in the U.S. Federal Register and Notes characterised as debt (or which are not otherwise characterised as equity and have a fixed term) for U.S. federal tax purposes that are issued on or before the relevant grandfathering date would be “grandfathered” for purposes of FATCA withholding unless materially modified after such date. The grandfathering date for (A) Notes that give rise solely to foreign passthru payments, is the date that is six months after the date on which final U.S. Treasury regulations defining the term foreign passthru payment are published and (B) Notes that give rise to a dividend equivalent pursuant to Section 871(m) of the U.S. Internal Revenue Code of 1986 and the U.S. Treasury regulations promulgated thereunder, is six months after the date on which obligations of its type are first treated as giving rise to dividend equivalents. If

199

additional notes (as described under Condition 18 (Further Issues)) that are not distinguishable from such previously issued grandfathered Notes are issued after the expiration of the grandfathering period and are subject to withholding under FATCA, then withholding agents may treat all Notes, including the Notes offered prior to the expiration of the grandfathering period, as subject to withholding under FATCA. Holders should consult their own tax advisors regarding how these rules may apply to their investment in the Notes. In the event any withholding would be required pursuant to FATCA or an IGA with respect to payments on the Notes, no person will be required to pay additional amounts as a result of the withholding.

U.S. DIVIDEND EQUIVALENT WITHHOLDING

Section 871(m) of the U.S. Internal Revenue Code of 1986 treats a "dividend equivalent" payment as a dividend from sources within the United States. Under Section 871(m), such payments generally would be subject to a 30 per cent. U.S. withholding tax which may be reduced by an applicable tax treaty, eligible for credit against other U.S. tax liabilities or refunded, provided that the beneficial owner timely claims a credit or refund from the IRS. A "dividend equivalent" payment is (i) a substitute dividend payment made pursuant to a securities lending or a sale-repurchase transaction that (directly or indirectly) is contingent upon, or determined by reference to, the payment of a dividend from sources within the United States, (ii) a payment made pursuant to a "specified notional principal contract" that (directly or indirectly) is contingent upon, or determined by reference to, the payment of a dividend from sources within the United States and (iii) any other payment determined by the IRS to be substantially similar to a payment described in (i) or (ii). The final U.S. Treasury regulations issued under Section 871(m) (the Section 871(m) Regulations) require withholding on certain non-U.S. holders of the Notes with respect to amounts treated as dividend equivalent payments. Under the Section 871(m) Regulations, only a Note that has an expected economic return sufficiently similar to that of the underlying U.S. security, based on tests set forth in the Section 871(m) Regulations and applicable guidance, will be subject to the Section 871(m) withholding regime (making such security a Specified Security). The Section 871(m) Regulations provide certain exceptions to this withholding requirement, in particular for instruments linked to certain broad-based indices.

Withholding in respect of dividend equivalents will generally be required when cash payments are made on a Specified Security or upon the date of maturity, lapse or other disposition by the non-U.S. holder of the Specified Security. If the underlying U.S. security or securities are expected to pay dividends during the term of the Specified Security, withholding generally will still be required even if the Specified Security does not provide for payments explicitly linked to dividends. Additionally, the Issuer may withhold the full 30 per cent. tax on any payment on the Notes in respect of any dividend equivalent arising with respect to such Notes regardless of any exemption from, or reduction in, such withholding otherwise available under applicable law (including, for the avoidance of doubt, where a non-U.S. holder is eligible for a reduced tax rate under an applicable tax treaty with the United States). A non- U.S. holder may be able to claim a refund of any excess withholding provided the required information is timely furnished to the U.S. Internal Revenue Service. Refund claims are subject to U.S. tax law requirements and there can be no assurance that a particular refund claim will be timely paid or paid at all. If the Issuer or any withholding agent determines that withholding is required, neither the Issuer nor any withholding agent will be required to pay any additional amounts with respect to amounts so withheld.

The Section 871(m) Regulations generally apply to Specified Securities issued on or after 1 January 2017. If the terms of a Note are subject to a "significant modification" (as defined for U.S. tax purposes), the Note generally would be treated as retired and reissued on the date of such modification for purposes of determining, based on economic conditions in effect at that time, whether such Note is a Specified Security. Similarly, if additional Notes of the same series are issued (or deemed issued for U.S. tax purposes, such as certain sales of Notes out of inventory) after the original issue date, the IRS could treat the issue date for determining whether the existing Notes are Specified Securities as the date

200

of such subsequent sale or issuance. Consequently, a previously out of scope Note might be treated as a Specified Security following such modification or further issuance.

In addition, payments may be calculated by reference to dividends on underlying U.S. securities that are reinvested at a rate of 70 per cent. In such case, in calculating the relevant payment amount, the holder will be deemed to receive, and the Issuer will be deemed to withhold, 30 per cent. of any dividend equivalent payments (as defined in Section 871(m) of the Code) in respect of the relevant U.S. securities. The Issuer will not pay any additional amounts to the holder on account of the Section 871(m) amount deemed withheld.

The applicable Final Terms or Pricing Supplement will indicate whether the Issuer has determined that Notes are Specified Securities and may specify contact details for obtaining additional information regarding the application of Section 871(m) to Notes. If Notes are Specified Securities, a non-U.S. holder of such Notes should expect to be subject to withholding in respect of any dividend-paying U.S. securities underlying those Notes. The Issuer's determination is binding on non-U.S. holders of Notes, but it is not binding on the IRS. The Section 871(m) Regulations require complex calculations to be made with respect to Notes linked to U.S. securities and their application to a specific issue of Notes may be uncertain. Prospective investors should consult their tax advisers regarding the potential application of Section 871(m) to the Notes.

Dealers Transacting with the Issuer

Certain of the Dealers and their affiliates have engaged, and may in the future engage, in financing, in investment banking and/or commercial banking transactions (including the provision of loan facilities) and other related transactions with, and may perform services for, the Issuer and its affiliates in the ordinary course of business.

Certain of the Dealers and their affiliates may have positions, deal or make markets in the Notes issued under the Programme, related derivatives and reference obligations in order to manage their exposure, their general market risk, or other trading activities.

In addition, in the ordinary course of their business activities, the Dealers and their affiliates may make or hold a broad array of investments and actively trade debt and equity securities (or related derivative securities) and financial instruments (including bank loans) for their own account and for the accounts of their customers. Such investments and securities activities may involve securities and/or instruments of the Issuer or Issuer’s affiliates. Certain of the Dealers or their affiliates that have a lending relationship with the Issuer routinely hedge their credit exposure to the Issuer consistent with their customary risk management policies. Typically, such Dealers and their affiliates would hedge such exposure by entering into transactions which consist of either the purchase of credit default swaps or the creation of short positions in securities, including potentially the Notes issued under the Programme. Any such positions could adversely affect future trading prices of Notes issued under the Programme. The Dealers and their affiliates may also make investment recommendations and/or publish or express independent research views in respect of such securities or financial instruments and may hold, or recommend to clients that they acquire, long and/or short positions in such securities and instruments. For the purpose of this paragraph the term “affiliates” includes also parent companies.

ANNEX 1 – FURTHER INFORMATION RELATED TO NOTES LINKED TO AN INDEX

FURTHER INFORMATION RELATED TO NOTES LINKED TO AN INDEX

The Issuer can issue Notes which are linked to an index pursuant to the Programme, where the underlying index is CPI or the Eurozone Harmonised Index of Consumer Prices excluding Tobacco as defined below. The following information provides a clear and comprehensive explanation to prospective investors about how the value of Index Linked Notes is affected by the value of the underlying index.

"CPI" or "ITL – Inflation for Blue Collar Workers and Employees - Excluding Tobacco Consumer Price Index Unrevised" means, subject to the Conditions, the "Indice dei prezzi al consumo per famiglie di operai e impiegati (FOI), senza tabacchi" as calculated on a monthly basis by the ISTAT - Istituto Nazionale di Statistica (the Italian National Institute of Statistics) (the "Index Sponsor") which appears on Bloomberg Page ITCPIUNR (or such other page as may replace that page on that service, or such other service as may be nominated as the information vendor, for the purpose of displaying the level of such index), provided that for the purposes of the calculation of the Rate of Interest and the Final Redemption Amount, the first publication or announcement of a level of the Index (excluding estimates) by the Index Sponsor for a given month shall be final and conclusive and later revisions of the level for such month will not be used in any calculations.

Eurostat Eurozone Harmonised Indices of Consumer Prices excluding Tobacco Unrevised Series Non Seasonal Adjusted

The Eurozone Harmonised Index of Consumer Prices excluding Tobacco (HICP), as calculated and published by EUROSTAT and the national statistical institutes in accordance with harmonised statistical methods (the HICP) is an economic indicator constructed to measure the changes over time in the prices of consumer goods and services acquired by households in the Eurozone. Following the Maastricht Treaty, the HICPs have been used as convergence criteria and the main measure for monitoring price stability by the European Central Bank in the Euro area, as well as for use on international comparison.

HICP is the aggregate of the Member States’ individual harmonised index of consumer prices excluding tobacco (Individual HICP). Each country first publishes its Individual HICP in conjunction with its consumer price index. Thereafter, Eurostat aggregates the Individual HICPs and publishes an HICP for the Eurozone, as well as a breakdown by item and by country. In any specific year, each country’s weight in the HICP for the Eurozone equals the share that such country’s final household consumption constitutes within that of the Eurozone as a whole for the year that is prior to that specified year. These weights are re-estimated every year in the January publication of the HICP.

HICP is said to be harmonised because the methodology and nomenclatures for the index of prices are the same for all of the countries in the Eurozone and the European Union. This makes it possible to compare inflation among different Member States of the European Union. Emphasis is placed on the quality and comparability of the various countries’ indices.

HICP is calculated as an annual chain-index, which makes it possible to change the weights every year. This also makes it possible to integrate new entrants, as in the case of Greece in January 2001. If a new entrant is integrated in a specific year, it is included in the Eurozone HICP starting from January of that year. The new Member State’s weight is included in the annual revaluation of the HICP.

HICP is published every month on Eurostat’s internet site, according to a pre-determined official timetable. Publication generally occurs around the 14th – 16th day of the following month. If a revision is made, it is published with the HICP of the following month.

Base Year Change

In Europe, the national statistics institutes change the base year of their price indices every 5 to 10 years. This procedure is necessary to ensure that the index follows changes in the consumption pattern through a new consumer spending nomenclature. The resetting of the base generally accompanies changes in the definition of household consumption that occur when the national accounting system is modified. Since 2006, the index reference period has been set to 2005 = 100. In order to obtain a common price reference period, too, the weights for each year are "price updated" to December of the previous year.
